That's a good one. But there are so many I don't know which ones to send you. Any particular interests? Even on Google, if you search for specific keywords you will find such sites, maybe after the first few pages. I maintain my own site with no advertising or tracking, and no intrusive javascript, but I don't know if it would interest you.

Here are a few random selections from my RSS collection:

• https://www.justuseemail.com/ • https://apenwarr.ca/log/ • http://www.stochasticlifestyle.com • https://jvns.ca • https://www.math.columbia.edu/~woit/wordpress/ • https://www.futilitycloset.com • https://retractionwatch.com • http://vihart.com • https://www.ex-muslim.org.uk • https://tug.org • https://lwn.net • https://prometheus.med.utah.edu/~bwjones/

None of these have cookie warnings, doorslams, or other annoyances. I have a over a hundred of these. There is more out there than you could possibly keep up with, even with RSS.
