Another user made the point: maybe you care about 3D printERS. The vast majority of people care about the printed end result, and buying more printers in the case of massive failure (which is already rare) makes more sense. If you're 3D printing for fun at home, a Bambu will basically never break.

Spending 3 days tracking down the parts for a Prusa, taking it apart, fixing it, realising some settings have gone to shit, fixing it? I hope you have a lot of time to burn in your personal and business life :)
