An argument could be made that this mission is politicising freedom of speech, in that a tech company is now determining what is misinformation and what is not. This very topic was a point of contention in the congressional antitrust hearings.
A company operates in a political environment, whether or not people want to acknowledge that. Workers have real power and can advance their goals whether or not management wants to accept it. Politics in the workplace isn’t something to shy from, but to embrace. Any company that tries to refute politics will find themselves behind the curve on something they should very much so try to stay ahead of.
I don't see how a tech company being the final arbiter on what is deemed misinformation on its own platform is politicizing free speech.
Yes you could stretch any argument to categorize anything as what you want, but I think under a reasonable interpretation of 'politicized workplace', Twitter could institute a policy of adding warnings to content it deems misinformation without politicizing its workplace.
As for workers having power, yes, but the company has the right to dictate what the worker does in their capacity as workers, if they choose to stay employed at the company.
Maintaining a mission focused company that doesn't allow employees to turn the company into a vehicle to advance a political cause unrelated to that mission is good for productivity.
