From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So … people misusing DoH – a system that makes it impossible to block or see the traffic because you cannot block port 443 nowadays and where it is by design that the individual clients and not the operating system handle DNS requests?
DoH was a mistake.
Yes, it isn't great how DoH traffic can't be controlled well. Apps using DoH makes blocking ads unnecessarily more difficult. (DoT solves DNS encryption better imo.) HTTPS is already often unblocked and also difficult to analyze, but DNS is already used enough for malware communication.
