I’d spend much of it selling them on Linux (mint is really not bad to use/install these days), libreoffice, lemmy (for the upvotes), Signal, Matrix, Jellyfin, and some of the amazing free phone games.

Let people know there are alternatives. So they migrate comfortably the next time a garbage product comes out, and are willing to look+donate when a new thing comes out that could/should be free as in freedom.

Security is mostly theatre, and the average person probably isn’t under much threat even doing everything wrong. But slightly more informed as a consumer and user could really make a positive impact on their lives + those around them.
