Thanks for that but it's unrelated to what the OP said which was "I find it unconscionable to do business with someone who would do business with Elon.".

Having an X/Twitter account is doing business with Elon. You could say only paid X accounts qualify for this, but I would imagine most brands have paid accounts.

YCombinator has an X account. I suspect the OP is already asking for his Hacker News account to be deleted.
