Not only does it acknowledges that Plex is still far better than Jellyfin with its whole ecosystem, but it also depict pretty nicely the entitlement of the users overall.
On one side, they paid $75 more than five years ago for a piece of software for which they still receive weekly updates. On the other, they talk about how leadership at Jellyfin decided to throw the blanket after a burning themselves out for free.
Up till now, Plex kept their promise regarding the Lifetime pass: we still receive updates, we still have all the features. So, unless they change that, they haven't broken their promise. It seems only fair from them to try to run a sustainable business, which you can do without renewed income. They have to find money. They raise subscription price: no impact on existing Lifetime pass owners. They add ad-supported features: no impact on existing Lifetime pass owners. I don't see a single add wherever I access my Plex library, I have hidden their "free" library. I still have 100% of the features I had when I bought the Lifetime pass. Except that I have now access to more features.
Sure, nobody forced them to say "Lifetime", but I don't see how I could be mad if they decided to release a completely new version that is out of the Lifetime scope. I would still have access to the old one, but if I was interested in the new one, I would have to move to one of their new plans, that looks more sustainable in the long run.
Plex is still the easiest one to use for regular user or for the people, like me, that act as IT support for their family and friends, and don't want to spend their evenings and weekends tweaking their aunt's TV just for the sake of using Open Source software.
