That’s an abysmally bad idea. This would be a wet dream for companies like Meta.

Effectively that would lock in the monopoly by huge social media platforms and absolutely no one would be able to try and make alternatives.

That idea would raise the bar for entry into social media to such a degree that only establish platforms can maintain themselves.

Which would make things like Lemmy, anything on the fedaverse, any third-party or fledgling social media platform…etc defunct overnight. And the only options would be existing, abusive, monopolistic, corporate managed platforms.
