It seems fair to use some amount of propaganda to push the "I want to work from home" agenda, since companies pushing "return to work" are also playing that same game.
I agree that he seems to have nuance on the topic, but the playing field seems to have already abandoned fair play.
It may be fair to do so but not necessarily effective. People tend to start tuning out what they see as hyperbole.
The companies may seem to get away with it, but not because they use a particular language tactic. They have the power to back up their "opinion" by firing people. People who want to keep their job may stop arguing, not because they buy the BS framing but because they have bills to pay.
The folks who hope to take a stand in the interest of worker's rights would be better served by trying hard to stick to the facts, promote nuanced discussions and not let the companies drag them into this kind of pissing contest.
