Hurt is a strong word but other people would be paying for that benefit.
It's not hard to imagine someone who decided to miss out on college and take the career penalty of lacking a 4 year degree just to avoid debt feeling like it's a bit unfair to have to help pay for other peoples degrees. People who made the decision to take on the debt.
Maybe it's would be a societal good overall but it's not like there isn't another valid side to the debate. Personally I think that money could be better targeted towards those in poverty whether they have student debt or not.
I think PWAs use your already installed browser whereas apps like teams use electron which bundles its own browser which a lot of people see as wasteful.
