What’s the psychology here that people are willing to pay this much for this software, yet not even $20 for another?
Also there’s simply more clients for it. The only way to play Bluray Dolby Vision layers correctly is with an AM6B+ which has an amazing Plex frontend.
Plex just works and is supporter everywhere. Not that surprising that people use it.
There are plenty of situations where a business must charge over X for one reason and must charge under Y for another, where Y < X. What happens is generally they go for the "over X" branch for fairly obvious reasons, then go out of business sooner or later because they can't actually charge that. Just the fact that they are trying to charge that much doesn't mean people are paying it.
