I don’t think you understood what I was trying to say: The difference is that companys wont do the skippable ads by themselves. Each country will have to do their own legislation to mandate this. Even if Europe would do similiar legislation to Vietnam, YouTube would still show full ads in other countries because they make them way more money. Which is quite the difference to hardware mandates like USB-C, where a few countries can basically set it as mandatory and the manufacturers will roll it out for all countries because its easier and cheaper to manufacture one model than multiple different versions. It makes no sense for Apple to produce one iPhone with USB-C and one with lightning financially. But it makes a lot of sense for YouTube to show unskippable ads in every country that allows it to make more money.
