Historically it was always interesting and quite challenging legal work, reconciling some things a bit like this with privacy, lawful intercept and anti-remote-exploitation-tool (anti-trojan) laws, especially in Europe (think: the cookie rule, which goes beyond cookies and PII). Then again, more recently mobile apps and operating systems (on all platforms, e.g. desktop OSs) seem to be doing quite a lot of it, so maybe those legal concerns were overblown.

I think its possible that the laws are still being violated, but good luck suing companies like MS or Google as an individual. Governments won't go after them because their spy agencies love the constant stream of data they can collect from it.
