Earlier quoted context omitted.
I'm firmly not in Trump's anti-DEI camp but I have seen what can happen when you make it one of your core values. You can end up with a lot of people talking about it a lot, lots of meetings and initiatives rather than doing actual work. And usually those don't go anywhere because the people doing it don't have any power to actually change things. It's unlikely that a company like Gitlab really needs anything changin…
Places I've worked that actually seem to have inclusion as a core value are great places to work and seem to have high functioning teams. My impression mostly though is more that it was never really a value for management but they wasted a bunch of time talking about it. In general any mismatch between stated values and actual values has been awful to deal with and is a red flag for places to work.
I am not sure if you had implied it but that would align with my experience as well: places that tout diversity were the worst places to work (as someone who is seen as 'diverse') while the ones that treated everyone the same and had the expectation everyone pulls their weight.
I absolutely despise people treating me differently because of who / what I am rather than doing good work. I will take mildly inappropriate good-nature jokes over head pats every day of the week.
