If money could stop things from enshitifying, there would be very few shitty things on the planet.
If everybody on the planet subscribed to YouTube premium they would still become enshittified.
Even with 8 billion monthly subscriptions at $10 a month or more, Google would raise the prices and provide less service.
They would do whatever they have to do whatever they can do to extract the most amount of money they possibly can out of the product.
This is not just because Google is a shit company, this is because greed knows no bounds. The only way for a company to stop being enshitified is for the company from the top down to be radically opposed to enshittification.
