I'm one of the weirdos that should be on board with this, but I'm against it. This will do harm to marginalized youth and push younger people to lie and find ways around the ban.
Plus, we saw that in Australia that the lobby behind the ban was in fact an ad agency that makes ads for gambling apps.
Here is France, the ban is probably just a way to avoid legislation against companies selling crap that isn't for kids like vape pens and sports gambling apps.
