Anthropic, for obvious reasons. Hard to imagine a more moral founding story, corporate vision, or governance structure, even if they've engaged in quite a few questionable projects along the way. Can you imagine any other company willing to get blacklisted from government contracts for 3+ years minimum just to take a moral stand?

Various companies dedicated to open source, workers coops, etc. -- but they might not count as "tech", depending on your priors. They certainly don't pay as much! Still, 80,000 hours is a great resource for anyone interested in the mainstream of that kind of thing: https://80000hours.org/

Google certainly has a good moral compass in the small, incidental things; the fact that their empire is maintained via monopolistic behavior and weapons of war more than outweighs that though, as does the fact that they are far less well-intentioned than they used to be. Watching videos of old AdSense training seminars in 2022 was a pretty radicalizing experience, I won't lie.

Microsoft has been leaning into moral arguments for their new AI branch to a unique degree, but I don't even give em partial credit there. They seem to just be cynically taking advantage of the popular sentiments about AI in the west (read: deep, virulent hatred), kinda like what people accused Meta under Le Cunn to be doing but real this time.

Otherwise... uh... nothing comes to mind. A company has to be a non-profit to truly qualify, or (like Anthropic) a Public-Benefit Corporation[1]; without that, they are ostensibly obligated to be immoral in the quest for profit, with the exact limits of that law being vague and extreme at best.

[1]: For clarity: the latter designation is 5% substantial legal justification for unprofitable moral decisions and 95% virtue signaling, yes, but virtue signaling is important! If a company can't be bothered to do some paperwork to show they're moral, they probably don't care all that much about it either as an honest intention or as a cynical strategy.
