Newbie: I just wish I could install broadcom packages to get wifi working

Hello! I really don’t want to start my own thread but have already asked on this forum elsewhere about any advice for how to get a Thinkpad L540 to work with PureOS, if possible.

Technically, I think the hardware won’t support free software for wifi. I checked H-Node - after finding that the Pure OS Debian link to hardware requirements (via OS Pure’s wiki). I am on Linux Mint but a bit creeped out about how much Ubuntu it uses (isn’t Debian better, for the privacy-minded, c.f.)?

Any thoughts would be much appreciated, thank you!
