For an excellent product, I am glad that Plex is charging an appropriate amount. Software development time, basic hosting for software downloads and login services are not free. The Plex clients getting onto so many different platforms I also imagine is quite a bear to get under control. Then, open-source alternatives still require overhead and maintenance from an admin - consider the $ spent with Plex the cost of your time.
There will always be inflation, and this does not seem like an excessive increase for "lifetime" membership. That being said, I am cautious of other "lifetime" memberships which have failed :
- American Airlines - AAirpass : scrapped when people took massive advantage of the number of flights, tied to a person
- TiVo DVR All-In Plan : scrapped when physical time-shifting media products were no longer feasible, the "license" was tied to the device
- Unlimited Web Hosting : scrapped when people really used the unlimited webhosts for unlimited data transfers, hidden limits are typically enforced to kick off the worst offenders.
- probably a lot more ...
Notably, some have really succeeded! ( and there are many more examples) :
- US National Parks Service - $80 Senior Lifetime pass ( must be over 62 to qualify ), tied to your death like you would expect.
- REI - $30 - a lot of in-store perks, and returns.
- Forever Stamps - fixed cost of mailing letters.
- etc ..
Here's to a lifetime membership that thrives!
