I upped the font size on my Pixel recently and this is one of those sites where (in Firefox) the sidebar takes up more than 50% of the width of the screen and retains tiny text while the article itself wraps on a couple words per line.
In the sprit of the article, "grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference."
Mentioning these things in a comment is neither accepting of how it is nor changing it. You can't change the site - the author died. You can change your browser or reading mode or whatever. Or you can just accept it is the way it is.
Maybe things have changed since I was an Android dev in 2013, but I buy Pixel devices because I don't expect something to work well on most Android devices if it doesn't work well on a Pixel.
I'm willing to switch between Chrome and Firefox. On Chrome I get 66% body content I can't read. It's one of the reasons I stopped using Chrome.
