I'm with you. It's akin to walking into a bar, seeing everyone peacefully drinking, and yelling that they're all assholes because the beer they're drinking Budweiser instead of something more ethical.
Like you aren't wrong, but who the hell are you to barge in and complain without even bothering to settle in? Can't just hang out for a bit, get to know us first, then bring it up later? It had to be the first thing we hear from you?
No, to me that's incredibly rude, and if it was my bad I'd say there's the door, go find one you like more.
