I didn't know it was called sideloading, I've been doing it for decades. Loaded my kids Kindle up with tons of books, he has an mp3 player I dumped a rip of all my favorited songs and ones he really likes, roughly 5,000 songs so far. My Plex is loaded up with newest movies immediately. We use stremio for tv series mostly.

I'm going to make a guide for how to get all this stuff for himself soon, no reason it needs to die with me. The legend will continue.

We've got a family steam group we all share games, but I do pirate some and download my purchases from GOG. I even go back and buy games after pirating them, Split Fiction was a great couch game we beat this summer and the developers deserved that money. Shit was smooth and fantastic.
