I haven't read any of his book yet, but I agree with a lot of his philosophy toward tech. For example, you can read here why he did not publish his recent book on enshittification on Audible, Amazon's audio book service, because he is against the DRM that Amazon requires: https://scribe.rip/@doctorow/kickstarting-a-book-to-end-enshittification-because-amazon-will-not-carry-it-7585250dabaf . He's willing to put his money where his mouth is, excluding himself from potential sales out of principle, and I respect that.

I also try put my money where my mouth is and support DRM-free media when possible, e.g. on gog.com and the DRM-free section of ebooks.com.
