As abhorrent as the actions of Trump are, I still think it's also a massive problem when a few private companies or even single unelected individuals like Zuckerberg who effectively control a defacto monopoly of public forums online between them can regulate speech as they please without any checks and balances whatsoever. Don't get me wrong, in my opinion Trump is a traitor to the USA and democratic societies as a whole, and did incite a portion of his followers to overthrow the elected government and parliament in an attempt to nullify the democratic election results and install himself as an tyrannic leader (and only backed down and told people to "go home" when he saw this would not succeed in an attempt to cover his ass"), and he should be impeached and convicted and removed from office and receive a jail sentence. But I shouldn't have the power to be judge, jury and executioner all by myself and put people in jail or even regulate their freedom of speech, and neither should facebook or Zuckerberg or twitter, or Trump for that matter. There is a rule of law and democratically legitimized institutions to enforce it, protected by a system of checks and balances, and it's the place of these institutions to make such decisions in accordance with the law. This time a lot of people will think the ban hit the right person in Trump. But next time it might be somebody less clearly (to us) deserving of such a ban (like a "traitor" Snowden or a "commie" Sanders). What, for example, if social media had been around in the Jim Crow era and the "rulers" of social media had decided that the civil rights movement was to be silenced? Or that "traditional marriage" is an institution that needs protection from "gay marriage"?
