It turns out the example of a math worksheet mixed with Maya Angelou questions is real.
But, after many objected, it was eventually withdrawn.
If you've seen the example of a math worksheet, someone years ago DID think this was a good idea, though it's a poor way to teach math and it's a poor way to teach reading and it's a poor way to teach about the the late, great poet, Maya Angelou.
From the ASSOCIATED PRESS, in 2017:
PERKASIE, Pa. (AP) — A Pennsylvania high school is apologizing after students were given a math homework assignment that asked which family member had sexually assaulted a girl.
The assignment focused on Maya Angelou and her autobiography “I Know Why the Caged Bird Sings.” It provided an algebra formula that asked: “Angelou was sexually abused by her mother’s ___ at age 8, which shaped her career choices and motivation for writing.” Pennridge High School students needed to solve the formula before deciding whether the answer was boyfriend, brother or father.
Screenshots of the homework posted by news organizations showed the subsequent question reads: “Trying to support her son as a single mother, she worked as a pimp, prostitute and ___.” Another formula must be solved to determine if the answer was bookie, drug dealer or nightclub dancer.
SNIP
A similar homework assignment caused controversy in Fort Myers, Florida, in 2015. In that case, a middle school teacher also downloaded the algebra homework from an external website. The district said the veteran teacher didn’t carefully examine the homework and called it an oversight that wouldn’t be repeated.

Over the past decade, at least three different school districts have been forced to issue public apologies because of a math homework sheet that contains content about sexual abuse.
The math “Person Puzzle” features biographical facts about the poet Maya Angelou, who died in 2014. The worksheet mentions sexual abuse and prostitution.
Outraged parents say the worksheet is not appropriate for high school math students. The controversial assignment has been removed and is no longer available for teachers to download for use with their students.
What the Worksheet Says
Until late February 2022, the “Maya Angelou Person Puzzle” was being sold on the Teachers Pay Teachers website. It was marked as appropriate for students in 10th through 12th grades.

I would be curious to know what other Person Puzzle Solving Systems with Substitution activities are out there. I mean I could construct one for Charles Lindbergh that would bring the house down. I mean would they object to a similar one regarding Ernest Hemingway for example.
Here is a partial one for Napoleon.
Nobody is going to wind up horrible at math because they were able to rely on their knowledge of Maya Angelou to skate through high school algebra. 
Besides, there is actually pedagogical value in that, too, as a supplementary approach. A hypothetical student who is not confident in math but is sort of confident in Maya Angelou facts could select from the multiple choice and then check their answer, thus getting practice at math (and potentially building confidence in so doing). Those kinds of exercises are actually really useful pedagogically, providing students who may not connect with a concept head on (or in the particular way that it is taught) the opportunity to sort of reverse-engineer their way into the concept. Now, an exercise like this on, say, an exam would be a different story altogether. But this is one worksheet. Not a curriculum.
But another point. We never ask why high school athletes need to run laps or do pushups. Why is there this idea that kids shouldn't have to practice math skills in a similar way?
This analogy doesn't work at all, for a variety of reasons. For one thing, nobody is saying that kids shouldn't practice math that way. (It's silly to judge one exercise as though it's a curriculum.) But there's also no reason that kids should *only* practice math in a similar way. Even athletes don't *only* practice by doing pushups or running laps or even doing skill drills. Coaches also incorporate all kinds of little mini-games and competitions (some of which include situations students would never encounter in a game) in order to break up the monotony and keep things interesting. Another difference, of course, is that athletes are a self-selecting population pursuing and approaching excellence in a particular discipline, whereas every kid in high school is going to be taking math class at some point. Similarly, nobody who absolutely hates basketball or thinks they're no good at it is going to be running laps or doing pushups at basketball practice, because the people who hate basketball or don't think they are any good at it are very unlikely to be at basketball practice. Those who are there probably don't (in most cases) love laps or pushups, but they're incentivized to push through it because they're motivated to get better at basketball and help the team succeed. A high school math teacher can't expect everybody in his third period trig class to be similarly motivated by the task. (A high school coach who also teaches PE is probably not going to approach basketball practice with the varsity squad the same way he approaches the basketball unit with the seventh-period sophomore PE class.)
other than that you think both the proposed CMF as well as any math worksheets that include non-math content are bad approaches to math education. On the former I'd likely find some common ground, but as I said that's a different conversation altogether.
