I mean, yes and. Companies may do things for broadly marketing reasons, but that can have positive consequences for users and companies can make committed decisions that don't just optimize for short term benefits like revenue or share price. For example, Apple's commitment to user privacy is "just marketing" in a sense, but it does benefit users and they do sacrifice sources of revenue for it and even get into conflicts with governments over the issue.

And company execs can hold strong principles and act to push companies in a certain direction because of them, although they are always acting within a set of constraints and conflicting incentives in the corporate environment and maybe not able to impose their direction as far as they would like. Anthropic's CEO in particular seems unusually thoughtful and principled by the standards of tech companies, although of course as you say even he may be pushed to take money from unsavory sources.

Basically it's complicated. 'Good guys' and 'bad guys' are for Marvel movies. We live in a messy world and nobody is pure and independent once they are enmeshed within a corporate structure (or really, any strong social structure). I think we all know this, I'm not saying you don't! But it's useful to spell it out.

And I agree with you that we shouldn't really trust any corporations. Incentives shift. Leadership changes. Companies get acquired. Look out for yourself and try not to tie yourself too closely to anyone's product or ecosystem if it's not open source.
