I think the issue Mantze is having is he wasn't just hosted on AWS, rather Parler was built on AWS proprietary software, so when they shut him down they kept the script, all he could get was his DB at best out of them.  Which is why it wasn't a simple move the site.  

At this stage I'd be surprised if Boonex wasn't reaching to Mantze to help offer him an overall solution to his problem.
