Yes, eventually, all of them will end up this way. But the attitude lacks nuance. I paid $120 for Plex 8 years ago, and if it becomes utter crap tomorrow, it's been totally worth it.

Don't think of any such thing as "lifetime". Just ask: "For the amount they are charging me, how long does it need to last for it to have been worth my money?" With the price I paid, one year would have been enough.
