so why should people have to see that on their computers in the first place?
You don't have to see anything online, (unless you are on a mind rotting infinite scroll). When you want to see something or play a game you have to actively seek it out.
This issue is that once there is a precedent set for payment processors manipulating markets they wont stop. Just like the zombies on tiktok that say "un-alive" because they thin the word "died" will have them kicked off the internet, publishers and developers will get nervous that their game may not sit well with a payment processor for some reason like religion, racial heritage, or opinions on sexual orientation and gender, and they will be unable to sell their game.
