I don’t use Plex, but I’ve seen a couple people mention this lifetime plan pricing increase. Mike Rockwell blogs:

But $750 feels insane. That’s more than ten times the price of the annual subscription. That feels like too high of a multiple to me.

That’s a lot to pay all at once. I’m not sure lifetime plans are workable for some types of hosted software anyway. I have plenty of server costs each month to run Micro.blog, and the subscriptions sustain that. If I want to keep running Micro.blog for let’s say 20 more years, it’s risky to have too much revenue upfront instead of later.
