I call them fake because they are always of a lower quality, and on top of that sellers pretend that they are selling you an original part (check eBay, AliExpress...).
I see your point, but I don't like the idea of forcing companies to sell you things they don't want to.
You can have it repaired using fake parts or parts salvaged from broken iPhones. If it breaks, that is.
If the phone doesn't break during the two year warranty period, I've found that it's unlikely to break later on. (you have to treat it well, of course...)
word and excel are slower when compared to the Google workspace counterparts. There's a very noticeable lag when typing. They should be ashamed of themselves.
