It's not so much about selfishness as much as it is about literacy. The objectively correct choice is to press red. With how this question is presented, there is absolutely no reason to press blue, other than thinking "well some people might press blue without reading the question so we should all press blue just in case". Putting yourself in what could potentially be a life threatening scenario to save a theoretical person who may or may not exist isn't healthy. I've seen a variant of this question that is, imo, much better - it labels the switches "good" and "evil" instead of "blue" and "red". It's a lot easier to rationalize that a lot of people will feel pressured to press the "good" button purely because it's labeled good imo, and helps show how much the way something is presented alters our actions based on our internalized biases. Simply presenting something as "the good choice" will push people to pick it without thinking beyond that. Like in a video game where you get good boy points for doing something morally awful just because the game's devs thought it was a good thing, so everyone just does the good boy points option and then complains online that they feel bad about being forced to do bad things to get the biggest good boy point number possible.

having what is effectively a "generate porn of this person and send it to them" button under every selfie or photo anyone posts was a very bad idea and crosses a line that a very, very large number of people are uncomfortable with. it's more an issue with image generators in general than with twitter specifically but it should be obvious to see why making it so in-your-face would draw significantly more attention to this already very controversial topic. grok makes targeted sexual harassment effortless.

The average person isn't going to see that. They aren't personally directly effected by any of that in their day to day lives, as far as they can tell. Minor inconveniences at worst for a lot of people. You feel cute and post a selfie, and suddenly get flooded with AI generated porn of yourself? You post a pic of your kids and suddenly get flooded with dozens of indecent images of them? That's something the average person is directly seeing and which directly involves them. It's targeted at them, specifically, in a way that is going to cause an immediate response. It's not some vague concept that someone somewhere is being censored for something or other, it's porn of them being sent at them whenever they post any pictures of themselves. It drags the majority of people who just want to go about their day and don't want to care about any of these things into it and forces them to care.
