It's a bit of a weird comment but I've had similar thoughts about what the Oxide Computer Company is doing could be a good use-case for Parler.
They're doing some awesome stuff around providing software to help manage on-prem infrastructure. They also have a fantastic podcast [0].
I don't claim to know what Brain Cantrill (one of the founders of Oxide) thinks about Parler's situation or their content but from some of his talks you can tell he's an incredibly ethically conscious person, so the commenter above is likely assuming he's not a fan of Parler.
