That well funded company already happened 20 years ago. Canonical. Their distribution is called Ubuntu, you might have heard of it.
But it would never work without my help. On the other hand, Windows wasn't working too well either and I just couldn't help with that.
RHEL was the most stable alternative I could think of when her Windows computer stopped being reliable.
I have setup rustdesk on it for remote support.
Second, they don't buy this kind of thing every week.
Linux has made a lot of progress since 2010.
If low tech ppl in family get phones, I want them to be apple, less work for me (not an Apple user). If they get a PC, I want them to use Ubuntu. Less work for me.
And if there's some work, I'd rather ssh into their PC and fix it using a shell with bash, then get annoyed with Windows and it's quirks.
