Are you sure you want Win7 or Win10 and Mint? 7 hasn’t been getting security updates for years, and 10 will stop getting free security updates next year. And none of 7, 10, or Mint have official Framework support.
Is Win11 privacy and other concerns really that terrible that you’ll give up security updates? And Ubuntu and Fedora so bad that you aren’t interested in official Framework support? Linux Mint causes issues for some people on FW16, and by adopting it you’re giving up some level of Framework support. They can’t possibly support every distro, and by supporting two they’re already making an amazing effort.
