Most people can’t put on a screen protector properly. I wouldn’t perhaps go as far as claiming replacing iPhone battery takes no technical expertise. It’s not hard but not quite easy either. In the case of iPhone there’s also that even if you do it properly the device still detects it’s not the original Apple approved battey so they limit functions on your phone such as battery health, true tone etc. New MacBooks does this aswell.

They probably need additional legislation to stop companies from locking down products when non own parts are used.
