His response kinda confirms it was exactly what it looked like:
“Frankly, they need better dirty tricks,” Musk wrote on the social platform X, responding to a post describing the “salute hoax” as “just another part of the ‘dirty tricks campaign.’”
“The ‘everyone is Hitler’ attack is sooo tired,” Musk added, with a sleeping emoji.
Yeah, I mean, it's obviously trolling to begin with. What he did is undeniably similar to the nazi salute, yet he dismisses that fact without even slightly addressing it. It's intentionally lazy, and trying to conflate less-apt Hitler comparisons with an incredibly applicable one. Because he knows this approach will work for his intended audience, and he gets to chuckle to himself about being untouchable.
