I don’t think having decent taste and not wanting my operating system UI to be hijacked by a website makes me a snowflake. Fanbois should have the option to turn it on rather than normal people having accessibility ravaged.
I suggest that normal people should add this code to all their pages to force people to turn it off - it deliberately inverts their dark mode / normal mode choices. Should a site be able to do this, I don’t think so, its not the end of the world but it is absolutely pointless and the domain of people who have run out of things on pornhub to get excited about.
