For PDF editing, there’s so many good open source products.

Absolutely no reason to be using Adobe just for PDFs. Waste of money.

Yeah, this is kinda BS.

Adobe don’t care. Nearly every design firm is going to ask you about your Adobe experience, so you can use their Adobe software.

Maybe some of their designers will use GIMP. But that’s like saying your office also uses libre office and Linux. Which is extremely rare.
