I've been thinking about this a fair amount over the past 5-10 years, and I think a lot of the issues that we have can be traced to our demography and specifically 'the zeal of the convert' along with existing cultural dysfunction that would have been addressed if we'd grown more slowly as a group.
There's a lot of discussion about tech as an industry, but much less about tech as a culture, encompassing people's lives outside of their work/career.
Most people who are into tech in their 40s-60s came into it via a strong interest as an adolescent or young adult, and a fair number of them felt misunderstood and/or were abused/taunted/bullied/etc by mainstream culture. Then they discover this part of the world where people think like them and things make sense. They make friends who see things in systems! They can argue with facts! They agree what is important to argue about! They agree that consistency in thinking principles matters! Etc. This means a lot of people in tech, particularly the ones who hold the most power (even outside of founders) are decently likely to have either a disdain of or fear of non-tech cultures due to bad experiences, feel that tech culture needs to be defended from outside influences who don't understand and would crush it, and are well... zealots about it.
The problem is zealots are really bad at accepting and pinpointing issues within a culture. They want to defend it beyond all reason because to them, that culture/group is their safe place. If someone is bad in the culture, it can't be a sign of something wrong with the culture (because the culture is a safe place). Instead, that person 'isn't a true X'. Or that person is just a bad apple. The other influence is that converts absolutely don't want to lose their place. In the case of tech culture, because we've intertwined the culture with a career, that means people being afraid of losing their career/network/etc.
This is a different than being born into something. The perspectives are different. People born into tech culture/grey tribe/however you want to label it get to see more of how the culture expresses itself in different relationships (including its problems). They see disagreements between nerd adults that aren't mediated with corporate or monetary power/status structures, they have a choice about how much of the culture they participate in or not (like how someone born Catholic who goes to Mass once a year at Xmas is still considered Catholic regardless). There's more wiggle room, and more a sense of how those virtues play out over an entire lifetime instead of being limited to how they're expressed in a workplace between the ages of 20 and 45. Depending on the particular situation, it's also possible to have someone in tech culture who doesn't hold any personal grudges against the other cultures they share space with.
Right now, since we're dominated by converts between the ages of 20 and 50 and we've grown so quickly, we haven't had the time to create the cultural guardrails that would allow us to do things like 'agree on what constitutes an abuse of power' or 'agree on what we should teach our kids about morals', etc.
And because of the lopsided age pyramid, we have next to no elders, which doesn't help either.
This is shifting slightly as the first generation of explosive growth is starting to reproduce, and soon they'll start aging out of the workplace and we'll start to see more contemplative behavior. It's already somewhat starting: there's hints of people reaching that stage in their lives.
(NB: Yes, I'm aware that the tech industry pre-dates the 80s, but demographically those numbers are minuscule in comparison to the people who joined during and after the dot com boom. My grandmother used punchcards and knew C and was born in 1934, but there just aren't enough people with that experience for them to exert a cultural pull. Almost all of the elders we do have are regarded individually: we know (or know of) those people, but that's different from 'I'm struggling with this moral question, I'm going to go ask John because he's both wise and will understand what I'm talking about enough to give decent advice'.)
