Actually the opposite, tons of ppl in the meshtastic community (Discord) berate amateur radio operators. I stopped even discussing the subject because of how much derision I observed or was subjected to. Lots of insults and nasty jokes in passing as soon as the topic even comes up whatsoever. Kinda like your post, actually - offhanded derogatory remarks about an entire group of people solely because of the hobby they're involved in.

The person in question has many radios in the background of his videos, so maybe the comment you've replied to is into something :P

Eh, it's a stereotype. In my opinion, they should always be questioned, especially when it's an unkind one like this.

Frankly I'm surprised to see this here. Hackers have had more than their share of hurtful stereotype applied to both our hobby and our personality. We should know better. But perhaps there's a generational divide at work there.

Yeah, you're right.

is it because amateur radio operators legally have standards they have to comply with?

Kinda, most hams are very rhadamanthine about following every tiny rule to the letter, or their even stricter interpretation of the spirit. The type of people who complain about young people not joining the hobby while insisting on maintaining strict licensing rules and tests. It's very much the polar opposite of hacker ethic.

This + amateur radio is designed to be open, no encryption, anyone can talk with anyone, and if you're "being stupid" (to not use other terms), anyone can tell you so.

The "secret, encrypted, private" chats correlate more with random "doomsday preppers", and younger non-hams (cheap, no need to get licenced). Many of those people buy (ham) radios too ("for emergencies", can't transmit legally anyway), but don't really contribute to anything. Emergencies are handled by trained groups of hams when/if they're called to help by whatever proper agency needs help with communications.
