It's not nearly as relentless as most people predicted. More importantly, it doesn't seem very effective. Is this the limit of the extent of Silicon Valley's power?
That last question is rhetorical - I can easily think of people I would de-platform if I wanted to help the Democrats. I'm just wondering what's their plan. They could be going a lot harder than this.
I know I moved to Parlor when I got sick of dealing with Twitter's bannings. I just got tired of dealing with it, and I'm sure other people are the same as me. I use Facebook maybe twice a year. Heck, I'm here on the .win network rather than reddit, that should say something. They will get their echo chamber that they so desire.
I do think there is one thing that will limit growth to new platforms, and that is the censoring of new platforms on current social media and the search engines. I'm pretty sure .win content isn't indexed on google. I think Bing is the only search engine to index it properly, and Bing is only ~10% of the market. Every other smaller search engine just uses Google results with their own frontend.
