Did the OP get it at all? That's one of the reasons to ditch Google. Collecting data, no privacy, down to the tiniest details....
I don't think THIS is an example of privacy invasion at any level. In fact this is an example that shows that not all data collection is, excuse me for my abuse of the phrase, _evil_. All these browsers are provided by Google, the user is free to not associate Google accounts with them - they work really well even without them. There is no major loss of utility if you don't. Installing a third party addon to sync bookmarks across varies installations (as I used to do in FF) is trickier, wasteful and unnecessary.
If I have to browse something that I don't want Google to know or associate persistently to my account, I use Incognito Window. It works really well for the purpose it was designed for.

May be you are right, Google is a company that deserves no respect and no users; but when you phrase your sentiments that way, you basically call the other person an idiot who cannot understand even a bit of the most easiest of concepts. And when someone like me, who shares the same views as the OP, reads these opinions we are alienated. Just like you swayed from a largely-neutral position to make your point, we sway even more to counterbalance and what we get eventually is a flamewar. And no I don't get it and may be I won't (probably the OP would feel the same way). I infer that I respect my privacy much less than you do to yours and mine. So even if this was a legit case poor privacy practice on Google's part, but if I (and the OP) feels that it isn't than either you should respect my (and OP's) opinion or give a little more verbose explanation while assuming I will be educated enough to read and understand your opinion.
