I consider all those pop-ups to be illegal. The use case in my opinion does not warrant pissing off users by distracting them via such pop-ups. Here I classify slide-ins the same as pop-ups. I don't even read what is written there since I already don't care. I kind of have to use extensions to workaround this spam. The EU bureaucrats are very confused here - they cost a lot of money and don't really improve much at all. Plus, when they hand over data to the USA from EU citizens, it already puts them at logical odds - either you are consistent in what you do, or you simply shouldn't act in an orthogonal manner that degrades the user experience via laws. That's just nonsensical.
