Sounds like some SERIOUS HOA overreach here....

2. The only thing I can think of that wouldn't be overreach is a situation like what my sister's development has.

They contracted with a provider for the whole development at something like 1/3 the cost and the payment is part of their maintenance fee. But the provider can back out of the deal if there are less than a certain number of users in the development.

So that would affect everyone's cost in the development over time. But that would be pretty easy to explain to the guy who wants to use the other service and it doesn't seem like they have done that. So it may be that, or it may just be people being assholes.
