If you can't trust them to act ethically on the small scale, why would you expect that to turn around once it gets to a larger much more important scale?

How many government sanctioned school bombings does it take for them to quit working with said government? For now we know that number is somewhere between infinity and 1.

It literally does not register as "unethical" at any scale to have different products or prices for different customer tiers.

The question of collaboration with USG is a much more complex one, but is not the one raised above.

Edit: I'll also add that I doubt any AI-doom people "trust" Anthropic per se. The entire angle of questioning – again – misunderstands the AI-doom argument. You appear to think that if companies behave unethically, they cannot be trusted and they will not produce good outcomes, inversely: if they behave ethically, they can be trusted, and they will produce good outcomes.

Any competent AI-doomer would argue that ethics or trust are essentially irrelevant.

The entire problem is that people can act totally reasonably, even ethically, and this is not a guarantee of good outcomes. Situations can be created in which completely ethical, reasonable behavior actually produces a bad outcome. You do not need to assume people are bad in order to produce a bad outcome, and inversely you cannot assume that you will get a good outcome from good people.

"Arms races" are one class of situations that often have this characteristic. "Bureaucracy" is another class that we encounter a lot in daily life. There's a lot of them!
