The companies that enshittify their service never actually care about their premium service. They provide a service which is good enough for free users and a pro version for power users. Later once they amass a critical userbase, they slowly make their free service shitty and ask users to pay to get their good-enough service back. Free users were their focus all along and these premium users are there just to pay some of their costs.
There are billions of free users available. All they need to do is strip-off few excellent features of their free model and hide it behind a pay wall annnnd voila these free users have now became their paying customers!
