It's true that the people arguing against the President's statements aren't necessarily arguing from a principled stance, but that's true of any group that uses the levers of regulation. The Terms of Service, to a company, is sort of like laws to a state. Laws are important because they are instruments that can be used by everyone, and the government in theory ought to consistently apply them.
Take anti-discrimination laws, for example: they were passed in the 60's to combat what was then rampant discrimination against Black Americans by private establishments, however because the rules are generally pretty unambiguous, they can be used today by white people if they are being institutionally discriminated against, for whatever reason. But the group of people that would have utilized the levers of that law to combat discrimination against Black Americans will mostly not be the same group of people that might use the same law to combat any discrimination that might occur against white Americans — Black Americans might even accept discrimination against white Americans and vice versa (we see this happen today). To the law, it doesn't matter — Black Americans can utilize it for their own ends, and so too can white Americans — and as a result we ideally have NO discrimination against ANYONE. It doesn't matter what each group's motivations are.
That's how Terms of Services should (ideally) work, also. Just because the reality today is that one group is using the ToS and working backwards to justify some conclusion, the same levers exist for all other possible groups, and we hopefully reach an equilibrium where the Terms of Services are consistently applied. Unfortunately that appears to be blind idealism because — as we are seeing — companies don't necessarily apply their ToS consistently.
However, in this case, I don't think it's that Facebook doesn't want to apply their ToS consistently. I believe it's that activist employees, and opportunistic companies feigning boycotts, don't want them applied consistently.
