I’ve started using {emailaddress}+{sitename}@gmail.com i.e. myemail+xyzCompany@gmail.com

That way I can at least see who sold my info. I wish I would have started doing this long ago though. Some sites dont let you use the plus symbol even though it’s valid though

I’ve been using linux for years, but in limited contexts. With switching my primary desktop over this year I’ve found it helpful to stop by my local library and checked out some books on linux. I’m combining that with chatting with a locally running LLM. I’ve also setup an extra Raspberry Pi I had laying around with Ubuntu Lite as a sandbox OS to tinker with.

Maybe consider a portable sandbox setup like this you could quickly demonstrate or share?
