Sure, you could put it on me for not taking a course in "media symbolism though the ages" but that would be a dick move. That is very much not the same as the swastika mentioned in Fionwe's strawman below.
Since I've been a small child I've had meetings with holocaust survivors every year. I've been to museums in Berlin and Jerusalem. I've even seen Indiana Jones. But I don't recall these triangles ever being mentioned. Doesn't mean they were not used but there is nothing especially Nazi about them. Red triangles are used as a warning sign on the road all the time in every country.
What, the Nazis have ip on them because they turned them around ? So it is not possible in your opinion that some UX/UI person decided turning the triangles upside down might make the poster look better ? It has to be Nazi dog whistling ?
