Facebook spent almost $17MM in lobbying efforts last year [1]. I wonder why governments doesn't exactly have an eagle eye on this...
The rank and file employees at Facebook have no say about this. Tim Bray leaving Amazon to no ill effect shows this.
We're talking about Facebook exploiting the human brain to increase time on the platform. The users have little to say about this, and as long as the users are there, advertisers have nothing to say to Facebook.
So that leaves Facebook answering to their own ethics. Yes. that's the problem.

This is where governments come in. Companies should behave ethically, but ultimately we shouldn't just leave it up to them. That's why societies have laws. What we really need to do is use regulation and penalties to force Facebook into ethical behaviour.
Of course, this isn't going to happen because there's no political will to do so, generally due to "free speech" or "free market" objections.
If you always go with the populist vote, like when users rioted about the news feed when it was first introduced, https://techcrunch.com/2006/09/06/facebook-users-revolt-face... then you may be sacrificing the long-term viability of your company. This harms employees, investors, and eventually the public. Are you saying that's not even a consideration at all?
We're not talking about "Facebook exploiting the human brain to increase time on the platform". You brought up Target and shirts. So we're talking about who has more agency, users or executives, in a general manner. That consumers generally only need to concern themselves with their own ethics, versus the complex entanglement of ethics at a company, gives users more agency to make choices reflecting their ethics.
A VP or even the CEO is beholden to shareholders, their employees, their advertisers, their own ethics, their users, various government regulations (and government interests that are not laws but what they prefer). So almost everything they do is a tradeoff.
