"No one is as qualified to fight for speech on Twitter as the person who's done it through the company's most tumultuous decade."

That's putting forward a ton of assumptions, none of which you cited supporting evidence for; length of time is quite a weak-shallow argument point.

Let's also bring up the fact that maybe they stayed in those positions so long because they were willing to take a knee to the fascists in governments, willingly toeing the line for them - so then therefore lacking principles and integrity - which is an unacceptable foundation to be fighting from for anything.

Quite the straw man argument you end with.
