Note: am not furry, but have worked with several.
I feel like infosec was one of the earliest "no one cares who you are if you have skills" user groups. Online, you were just a handle. Man, woman, both, neither, no one knew until if/when you met up IRL. Until then, all you had was your reputation. I think that led to people having a pretty good idea about the attitudes of people they were talking to online, staying away from people who were going to be jerks about identity or pastimes, and a lot of conversations like "General Mayhem is weird, but he's our weird, so no one mentions that fox tail he wears everywhere."
Over time, that was a positive feedback loop: people who weren't cookiecutter felt safer around infosec folks than most other crowds. => That increased the "weird density" of infosec meetups. => People who don't like being around uncommon appearance or behavior stayed away from infosec meetups. => Those meets became safer for uncommon folks. => Repeat.
I don't know if that's right, but again, that's what friends have expressed to me before. It seems plausible.
Note: When I say weird, I mean it affectionately. I've never met anyone in infosec who didn't have some quirk not far below the surface. Frankly, I love that. And because of that, and the virtuous circle I described, I've never had one single person in infosec confess to me that they weren't OK with gay or trans or furries or other type of behavior/identity/etc. I'm a straight white middle class dude, and unfortunately I have had people confess such things to me in other circles, mistakenly assuming that since I was in their demographic, I'd agree with them or at least be OK with it.
Q: Why do rightwing websites keep getting hacked?
A: Because none of the best infosec people want to work where their friends wouldn't be welcome.
They don't get hacked specifically because of who they treat poorly, but because the very people who they treat poorly won't work for them. The subset of the population of whom they are publicly abusive and disrespectful is over-represented in the top performing defensive programmers.
point A > They wont hire from this subset of the population - which excludes a significant portion of infosec top talent. The neurodivergent talent pool that is adjacent to that subgroup, which itself may not be the direct targets of the abusive behavior is also over-represented in the top talent pool is less likely to feel comfortable supporting these clients.
point 2 > The remaining talent pool is thus a less concentrated distribution of top performing infosec professionals. Not that any individuals in this group are less capable in particular, but that the mean distribution of capability is somewhat lower in the remaining group.
point D > Hackers are prolific and adept at finding the least secure aspects of infrastructure, by definition. The concentration of talent in the hacking community probably follows the same distribution curves. This creates a subset of hackers with a motive to target both the less well prepared organizations, and have a negative opinion of those less prepared organizations with a history of abusive behaviour towards groups with which the subset of high performing hackers strongly identify or associate.
> Bigots, racists, far-right-wing Republican organizations get hacked. [Perhaps more frequently - unsubstantiated]. Apparently, because the outcomes of self-identification as intolerant asshats makes their specific infrastructure both an easy target for hackers of any orientation, and a preferred easy target for hackers opposed to bigotry, racism, and far-right-wing Republican organizations.
Period
And sometimes not even then! Which is fine because indeed, who cares :)
It's far easier to be transphobic / racist / furry-phobic if the first thing you notice about a person is their gender / race / furriness.
If you are that kind of person, you immediately get into the mindset of "what they're saying isn't worth listening to because they're a <slur>, and <slur>s can't be smart by definition." If you first meet them online, you picture them as smart in your head, before you learn that they're black / trans / furry. When you do learn about that, you already think that they're smart, so it's much harder for your brain to dismiss them just because they're something you don't like.
The "missing link" correlating furries (and trans women) with hardcore programming and is autism (and related conditions).
Autistic people tend to be very good at this kind of work, and are also more likely to find the social dynamics of these particular groups welcoming rather than off-putting[1]. You find the same overlap to a lesser degree with competitive Pokemon, LOTR, retro gaming tech, political extremism or other autism-adjacent interests.
[1]Many Autistics trend to feel much more comfortable being in groups where people don't adhere properly to social norms, because it means they're not going to be singled out and ostracized.
