PC - Path of Exile - This is an ARPG similar to Diablo 2. It has very well defined terms (outside of a few edge cases) that help guide your build creation. Lots of community support. They release a new league with content and updates every 3-4 months. While F2P, stash tabs are a useful purchase if you enjoy it long-term. I've been playing since 1.0 (over 10 years ago now)
Android - Idle Obelisk Miner - There is some initial manual mining, but then you'll unlock drones and bombs for mining. It's better as a screen-on idler, but can be played screen off, but much slower. In terms of an idler, I feel the pacing is done very well. (30 days of play time in game as of now)
IANAL, but I don't think he's claiming he doesn't own the business, but that the "offers for sale a variety of products and services designed to circumvent and bypass Nintendo's TPMs" is wrong. The only argument I can see at this point is "The TPM ceases to be Nintendo's after the customer purchases it". I have no idea if that's his angle or if it's a solid argument.
