Reread my comment. Your “own” is completely inaccurate

Or do the sensible thing and minimize how many accounts you make on various sites because they’re bullshit, which also has the added benefit of giving you a small enough number of accounts that you can remember the passwords

Ah, yes, because self hosting is feasible for everyone

/s if that’s not obvious

Single point of failure and a separate entity has all of your passwords and you have to continue paying them or lose access to everything. Sounds like a terrible idea to me
