Turn off DoH, Firefox
This is painful to read. Masses off unfounded FUD - the article deliberately buries that it's trivial to change your DoH provider if you're silly enough to believe that CF is actively logging DoH requests and selling them (CF is involved with serving vast swathes of the internet anyway - if they wanted to go down this route they have far more lucrative avenues open than selling DNS requests by IP).If instead what you worry about is the government spying on your traffic then complaining about DoH is even more silly - DNS requests are routinely intercepted and monitored by ISPs in many countries, with the information available to the security services, who have very few restrictions on what they are allowed to do with this data.  This is especially true in the country the author appears to be based (Germany).DoH is vital to protect users around the world from censorship and worse.  Enabling it by default is a good thing - protecting users from abuse shouldn't only be opt-in. There has to be SOME default chosen, and the default needs to be a site large and well run enough to a) handle the load, and b) be in the firefox HSTS preload list.  There aren't a lot of good DoH providers that fit these criteria - CF is one of the few.
