Maybe, maybe not. But in Facebook's case, they did not hesitate to commoditize disinformation and propaganda.

While a lot of platforms are/were susceptible to this vector, we now know that Facebook knew what was happening and didn't care as long as the money came in.

Which brings us back to "maybe, maybe not." Corporations use profit (and variants) as their natural reward function. Look at FBs stock the last few months. People are speaking. We, the users, may be demanding some accountability from our platforms we previously did not.
