Well I don't know if there are any deepstate involved as suggested but my personal experience is, Chrome gives me the most trouble-free browsing as far as dealing with government sites, medical sites, etc. Just last night I was using Safari to access a medical site and a pop-up wouldn't work and I had to go back to Chrome. My theory is, Windows' market is still the largest and developers write, put their effort into the largest OS, Chrome essentially came from Windows.
Ya, it may as well that Chrome is the biggest seller of your data. When things calm down, I shall go with a fine tooth comb and go through the procedure, "50 settings one should turn off in Chrome."
