The thing is, you're always going to dependent on someone in the mainstream economic world if you want to have a web presence in North America. Even if you run your own servers, you're at the mercy of your hosting provider, your ISP, your DNS registrar, and even browser level things like Google Safe Browsing. Any of these can be major points of failure.
So yeah, not using AWS would avoid being dependent on AWS, but you're going to depend on someone. In this sense, inclusion on the internet ultimately has a political dimension. I think that's just how it is — we live in a society with politics.
(I'm omitting commentary on Parler in particular because I have no sympathy for them in this or any other case.)
It's pretty baffling how people all of a sudden expect Fortune 500 companies to not act "politically correct" when bad actors are breaking their TOSes. Was there ever a medium backed by a large corporation where you could post calls to violence against politicians without getting booted off?
Twitter, Facebook, Youtube come to mind. The two that immediately come to mind would be Kathy Griffin holding Trump's severed head and Eminem shooting a Trump look-a-like. Neither were deplatformed for these graphic depictions / calls to violence, and one even reposted the offensive media in November.
Kathy Griffin's career still hasn't recovered and this was imagery not a call to action. I find it funny when Griffin gets brought up as if she wasn't "cancelled." Its an example of even treatment not hypocrisy.
TBH most "Free speech" platforms will allow anything except fraud, child porn, and calls to violence that violate criminal law. Baring all of that. There are still places online to host whatever you want.
It's mixed and depends a lot on how far they go into the unmoderated depths. Gab and Parler for example are US company while there's 8kun/chan that are overseas and go/went way further into illegal content.
