The effort is appreciated and while some brands can definitely be undoubtedly terrible (like Apple which doesn’t have a single phone the expressively allow you to unlock), many brands have a mix of phones that allow unlocking.

I’d much rather have a long table I can filter and sort than just a blanket “this brand is terrible and should be avoided”. Also, that verdict should be reached by a list of common criteria with a point system. It should just be the author of a page that decides a company’s rating.
