Its not Foss, but gog.com is based in Europe. It offers DRM free games. Lots of old games, but also tons of new games as well.

So my grandparents had somehow signed up for a free trial of office or 365 or whatever. They ended up getting locked put of opening documents because they didn’t want to give the computer their credit card. I was able to fairly easily convince them that Libre office was the was to go. They were pretty thrilled.

I’m thinking of giving them a linux PC to try out at some point as they mostly use it for Facebook and excel spreadsheets anyway.

Same. Haven’t had any problems.
