One of the problems with regulation is that politicians "understand" complex systems like computers or software or "the platforms" almost entirely by way of analogy. Yet at the point of actually introducing rules about (for example) tracking or what happens to your data, you need to throw away analogy entirely and start talking and thinking (and implementing) not an analogy but what the thing _actually_ is. Rarely do they resolve down to this last stage where you move from analogy to how things really work, or might work. I see this everywhere I have touched government and regulation over many years.
