I agree that it's deliberate, and I extend that to any sort of mining - after all it comes from the stance of misinformed "environmentalists" not being able to tell the difference because any of that type of action is bad
There are certainly people reposting comments that mix up lithium and cobalt and keep asserting that all EV batteries use cobalt and how terrible that is. They are not all environmentalists. A lot of them are just using those talking points as a way to oppose the move to EVs.
They also like to post a photo of an open pit gold mine in Australia and claim that it is a lithium mine while complaining about the massive environmental impact. they never respond when I post a link with proper attribution showing that it is not a lithium mine.
