Has Free Speech gone down over the past 40 years?

The cartoon below was printed (without any uproar) in a French teen cartoon magazine in 1973.

Jesus Christ, R. Wothan, Mr. Jupiter, Louis Buddha, Claud Allah and Gaston Jehovah getting drunk.

That magazine still exists (PG, not R). And there was no uproar.

42 years later, French cartoonists get mowed down for roughly the same fun cartoons.

My question is simple: 1973-2015: Has Freedom receded?
