You’re again correct, they use a lovely little modifier we call in English “And”. It lets you do two things as one thing. So you can legalize something, and regulate it, in one legislative action. But you couldn’t regulate something, and then legalize it, because if the government is regulating something they’ve defacto legalized it. If it’s illegal it can’t be regulated because the only regulation allowed for illegal things is “none at all ever”.
When a piece of content that doesn’t allow downvotes, like a tweet, has lots more reposts than it does likes, the “ratio” is seen as proof the opinion was disagreed with, proportionally to the “ratio” itself.
