Quit WFH job, still have laptop after 6 months

I quit a WFH job 6 months ago, and was told they would send me a box to mail in my laptop, but never received anything. I know someone else who left in January, and they never sent him anything either.

Company is fully remote, with an “HQ” around 1,000 miles away from where I live. No company software installed, everything was through Google suite. Browsers have a tracking add-in that monitors what you do, I can’t remove it and if I uninstall/reinstall the browser it shows back up.

I rarely use a laptop for personal use, most anything I do can be done from my phone, but thinking about turning it into a plex server to host personal media vs going out and buying a computer. I really want to spin up something like plex, so it seems like a win if I don’t have to buy a computer and just need to get the storage.

If this were to hypothetically happen to someone, WWYD? Other than the “remote” off chance they actually ask for it back, anything to watch out for if I go the plex server route?

Edit: forgot to add this was with a startup, not sure if it’s relevant. I was only there around 6 or 7 months before realizing they were never going to stop hemorrhaging money and my equity was worthless.
