That doesn’t matter. You only need to worry about boycotting things within your control, like Amazon shopping and their consumer products. AWS is profitable, but so is Amazon.com.
Buying something at a different store is always a dub even if that store is using AWS on the backend.
If people knew what the Nazis were planning to do back then, they might have boycotted BMW and Mercedes too, strangling them in the crib. Americans know what Nazis are; they were literally our biggest enemy and our greatest military victory, and the vast majority of Americans oppose Nazis. I think the only hesitation seems to be that people either don’t believe Elon actually is a Nazi, or that they think he’s just “TrOlLiNg ThE LiBs!!!11”.
That really sucks, and I don’t think you are a Nazi… but you’re driving a BMW in 1933. You’re not going to get any sympathy from people on the right side of history.
