Photographers don’t pay that much for inkjet inks. They buy commercial grade printers which cost a lot more up front but have much cheaper continuous feed ink tanks.
Only naïve consumers pay those highly inflated prices for ink. Those people should be buying a cheap laser printer but they’re not well-informed about the situation and so they get the cheapest possible printer which happens to be an inkjet.
I’m sorry you feel that way. I immediately felt at home on Lemmy. It legit gave me the feelings I had back when I first started using the internet in the mid 90’s. I thought that internet I knew was dead. But it seems a piece of it still lives on.
