When Morty stupidly agrees to all the legal terms of a new app and legally signs his life away to a faceless and unheard-of company, they immediately seize control of him and his life for their own purposes.
Then, when Morty screws up Rick's rescue effort, the company steals Rick's portal gun and strands our heroes in an unexplored dimension--leaving them free to strip-mine every aspect of Rick's inventions and the Smith family's lives for evil, capitalist purposes!
