Because the place many flocked to, Parler, has a sketchy reputation for uptime and availability. First they get kicked off AWS, and now a supposed "upgrade" that was supposed to take a few hours has stretched into Day #3 of downtime/unavailability with no communication from Parler as to when they'll be back up.
Mark Levin was talking about this two nights ago on his radio show that he left Fascistbook and Twatter for Parler and now Parler is "nowhere to be seen." His own calls and emails to Parler's CEO have gone unanswered and Dan Bongino doesn't appear to be talking about why Parler's been down this long either.
As soon as Parler comes back up ... if it even does ... I'm deleting my account there. I've never been on Twatter and I'm not going there. I'll keep my account on Gab which seems to be far more reliable.
I get that there is no alternative to Twitter, but if Twitter is going to ban or censor conservatives while allowing leftists free rein, it should be unacceptable. Sucks, but that's the way it is.
