I paid many movies on iTunes, and there's no way to access that content anymore, certaily not from my Linux (main) machines.

Also, people who "bought" 1984 on Amazon only to see it disappear from their Kindle will not have been amused.

Nobody likes to have things they spend money on cluttered across 20+ services with changing subscription fees and licensing terms. It's a mess.

All my devices run Linux and apparently there is no amount of money that will let me stream paid content above 480p.

There's no reason Netflix and Hulu couldn't both have ALL media available. Then they could actually compete on features and capabilities, not on media catalog.
