yea it sounds like a reasonable IT person at Parler would suggest preparing for getting booted off these big tools (aws, twilio, etc.) considering Parler sounds like exactly the type of product that would get kicked off these services.
One of the founders of pirate bay had a tweetstorm recently where he was like, i get that aws kicked u guys off, but like, u guys cant get a homepage up and running? I agree with this guy.
parlor was founded with politics in mind, maybe they are ok with shutting down their community because in a way that serves their political goals, sounds like parlor and aws are already suing eachother, i dont doubt uber-conservative users will find an alternative platform to use in the coming weeks.
