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.

This isn't really a "Linux" problem. Calling it a Linux problem implies all distros do the same thing out of the box because it's a part of the core system. Systemd has a file,
/etc/systemd/resolved.conf
which has one lineDNS=
that you can add the servers you want. It's as simple as that. If you're using Dnsmasq for DNS instead, you'd edit the Dnsmasq file. If you're not using my of those (i.e. you removed systemd-resolved, Dnsmasq, etc) then you can just edit the/etc/reeolv.conf
directly without worry of it being overwritten.While many distros come with systemd out of the box, not all of them do. For example, I use Gentoo with rc and after editing my resolv.conf, never had to worry about it again unless I decided to install a custom DNS software on it later.
I read many replies to your post as "DNS software shouldn't be allowed to change DNS settings" for the most part, and that doesn't quite make sense to me. If it's a problem, remove said software. Browsers are definitely annoying in the DNS front, I won't disagree with that. Fortunately, they allow you to turn that off though.
