Unfortunately not understanding or being sufficiently motivated by the threat of corporate social media is still prevalent among a good amount of lefties I know, but I find even when they are uninterested in leaving corporate social media they can at least understand the logic behind it in a way a lot of techy type people start to just get combatitive when you try to explain.

Most often when I have a conversation about this with someone who is very technically well versed with computers and the types of systems that are relevant to federated social media their response is to answer every one of my broader ethical questions by changing the topic to a conversation about technical details and they either utterly miss the point or outright refuse to have a discussion about it because they think I am being too cynical.

Ultimately these people only have one real argument which is to just repeat the mantra "stop being so negative, lets just wait and see before we jump to conclusions" endlessly about the same cycle of bullshit repeating over and over again.

I'm not sure I see the distinction you're making here. Usually those groups are highly overlapping.
