"I see you're complaining about society and yet you participate in society! Very interesting! I am very smart."
This is not a good or reasoned take. People organize where the other people are because that's how you get the most people. It is nor hypocrisy to use Facebook as a platform to organize protests against other tech companies. Just as it is not hypocrisy to criticize the society you live within.
This is a very stupid observation made by people who can't be bothered to consider the realities of life away from their keyboard.
It is a good or reasoned take (but perhaps not both!). There is some sliver of hypocrisy in condemning tech companies wholesale while enjoying their products. But just because something is hypocritical, it doesn't invalidate all related criticisms. If you don't like the negative byproducts of a good or service, that's a perfectly valid gripe. But those byproducts are a necessary consequence of the status quo. In order to eliminate or mitigate the undesired consequences, some change would need to occur in the real world that would require a hitherto unforeseen innovation or it would otherwise increase the cost of providing the good or service, potentially so much so that prices would increase to undesirable levels, or it would become economically unviable to produce the good or service entirely. So without more specific criticism, and combined with polemic rhetoric, it's reasonable to assume that some are arguing that the world would be better off without AI datacenters and the models they support entirely. And if those same persons enjoy those same services, it's reasonable to sense some tension there. Maybe they haven't thought the whole thing through. I don't think it's a stupid observation.
