I clicked and there is absolutely is content that is not acceptable, to me, visible on the front page. Everyone has a different opinions of what’s acceptable, which is why we have ratings systems so society can draw a line.
If a platform doesn’t curate then governments or the legal system, or lobbyists targeting payment providers will step in.
I see a lot of violent stuff, which I think many parents wouldn't find acceptable. I also see a little bit of weeb shit, which again may be unacceptable. I don't see anything which is obviously pornographic; the closest I see to that is an ad for Witcher 3, which I know to have nudity which could reasonably be called pornographic, however nothing in the ad hints at this. It is clearly a violent game though.
And again, studies have shown violence in video games does not increase violence in kids as they grow, in fact it tends to be an outlet, so it should be up to parents to control what they see as acceptable for the kid they are raising.
This push for governments to restrict EVERYONE's kids because a group of parents dislike something is insane, if you don't want your kid to play/watch something, the enforce some damn rules on your own kid.
Then .. don't let your kids use those games? Why should my kids be restricted because your puritan sensitives were upset.
