I totally get that the couple of bucks a month is worth saving any headache from doing tech support for family members.
However, if you want to try switching them to pirated sources, Stremio + Torrentio add-on and a Real-Debrid sub (which is paid but much cheaper than a streaming service) is great for giving you a Netflix-like interface for pirated content. It's easy enough that I coached my dad on how to set it up via text.
