I don't think this second assertion is true in 2019. See if you can make 
even a first-order reasonable guess what I'm accessing at 172.217.1.129 
or 23.227.38.32 or 52.40.19.98 or 216.105.38.15 or 104.20.1.85.

(Hint: I took these all from sites I visit frequently, and none are 
particularly obscure sites)
