ISPs complain that they use the ability to see DNS queries to
inject ads, spy on their customers and make extra profit selling this data - aggregated or not. Also, they complain that they're being "nudged" by various "law enforcement agencies" to complain, but can't say that publicly.
Anyway, we can expect "THINK OF THE CHILDREN!!!" and "TERRORISTS!!!!" to appear in the line of arguments, if they haven't yet.
Now, gospadin Putin, my daily paycheck please!
