Mildly relevant - the Telmate Terraform provider for Proxmox [1], which now stopped working with latest Proxmox version due to seemingly being abandoned, was initially mostly developed by an engineer employed by a company of the same name. They've since rebranded [2].
I've used that provider for a while, and only recently started looking into the specifics. The repo is effectively owned by a company profiting off of incarcerated persons in the US. Pretty wild.
Mostly writing this since I've spent the last few days migrating my Terraform setup to a different, supported provider [3].
