I really couldn't disagree more. With no satisfying underlying principle guiding this decision, this is absolutely not ensuring the longevity of -anything- in its current form. We're still in a state of complete disequilibrium, and Facebook remains a big juicy target for Ambitious Regulators, Aspiring (or Degrading) Politicians, and Culture Warriors. All we've done is reaffirm that the social media empires are taking more seriously their holy role in deciding what thoughts are permissible, no longer worried about exercising any humility due to the social status of the Thinker.
That said, I don't think the decision makes any of this worse. It is probably a tactically clever thing--ban POTUS when there isn't enough time on the clock for the full legal issues to flesh themselves out, while everybody is too busy with A Crisis of Something Else to focus on litigating it in public, but giving yourself something to point to to show you weren't Complicit during the Age of Orange Hitler.
So, as far as what it means for the value of the business? Probably not huge, maybe a very slight positive? But considering how monumental this shit is at the layer of "society", I'd say the civilizational uncertainty makes me wanna dial the correct multiple for everything back a bit.
