Not sure what your point is with tweets and articles from 2016 and 2017 but whatever. As far as echo chambers. No more than Twitter with the exception of not getting banned, shadow banned or suspended for opposing views…. Neither gab, Parler or Gettr is stopping anyone from joining. So again, what’s your point?
The Malkin post was related to Gettr immediately banning Nick Fuentes and others on the right, without any explanation, which is doing the ADL's bidding. The other posts reference Gettr's CEO Jason Miller working for CNN and the Clinton's and Gettr's global communications director Ebony Bowden calling Trump and, by extension, his voters, like many who post here, purveyors of hate, racism and sexism. Bowden also tweeted support on January 6, 2021 of joe Biden. My point is that Gettr seems to be run by some CINOs, conservatives in name only.
Beyond Twitter/Gettr, I mentioned that Gab has some great qualities that separate it from everything Twitter-like although Gab is an echo chamber, in this case meaning it's almost strictly a conservative site, which isn't necessarily bad, but it's preaching to the choir.
Nick Fuentes banned, caught live, as it happened, within 50 minutes on gettr:
