Roughly once every 18 months people panic about almost exactly the same boilerplate terms that make online services actually work.
This week it's Adobe, but honestly you could put 1000 different companies into a hat to predict the next one.
Yeah, none of that is new and every bit of that clause is completely standard and nothing to be alarmed about. It does not give them rights over "anything on your computer", it's just necessary because their service allows you to embed files into documents you upload to their service.
And it's so frustrating, because sometimes a rights grant clause *is* horribly written and overbroad (eg bsky.app/profile/raha... ) and people panicking over every single one means those go unnoticed!
I am usually the person saying "that's absolutely standard in a rights grant clause and nothing to worry about", which I mention because when I say "holy shitballs that's a wildly overbroad rights grant clause", you know I really mean it. This is a wildly overbroad rights grant clause.
