This is not Microsoft. I haven’t updated my plex software in over six months and it runs fine. Still, yes, I would expect updates to any software I purchase as new patches are needed for OS updates, etc. That shouldn’t be more than two updates a year for a given OS - if at all.
Selling a product, generating revenue, using revenue to improve products or create new products is how we used to run businesses.
If they’re unable to maintain software updates with the revenue they get, then they should discontinue support of less popular products.
As I’ve stated on the plex forum, plex is no longer a media management and consumption platform. It’s a video on demand service. That’s their prerogative and that’s fine. The issue is that they’re discontinuing a product that people have purchased and use on a regular basis. I paid money for a product and that product can no longer be used if I change the device I use that product on. They should have left the existing product alone and released something wholly new.
This guy on YT recorded the entire process of signing up for the mobile service. It was interesting https://www.youtube.com/watch?v=KUtSo7dASg0
