Interestingly, corporate PACs are withdrawing their support for enablers like Hawley, etc.:

Others are halting all campaign giving. Of course, corporate PACs should be done away with completely, but they're a gift from SCOTUS (corporations are people, too!) that isn't going anywhere soon.
But the shutdown of Parler, and more particularly, Trump himself on Facebook, Twitter, etc., raises an interesting question we all need to look at.
Do we want our speech adjudicated by a small cadre of companies?
They had to do what they did to shut these insane voices down, but we'll need a better solution in the long term. I haven't looked, but I bet the EFF (Electronic Frontier Foundation) is going batshit right now. I have no idea what a long term solution looks like, but I expect a discussion and some ideas to emerge soon enough.
I actually see the shutdown of Parler as less problematical than shutting down a president on Twitter and Facebook. Parler was a mess of an app for a lot of reasons, from authentication and encryption issues to its now well known call to arms. But it is not uncommon for app stores to shut down apps for various terms violations, so it's really kind of a non-issue. Certainly not a censorship issue.
The shutting down of Trump's accounts, which I am thankful for, given we have no better way right now, is a larger concern. I am not comfortable having these communication monoliths arbitrating free speech. They aren't comfortable with it, either, which is why they got into hot water in the first place.
I'll be interested in seeing how folks sort this out, since I'm clueless on an answer.
