I’m gonna have to read that one!
Umm, I really do admire HT’s books. Was unaware of his politics. I’ve been collecting SF books for decades — some go back to the 70’s. Am now in process of liquidating the ~5k copies.
That said, there is a way to avoid buying books from authors/outfits (e.g., Amazon) you loathe. I replaced most of my hardcopy books with electronic copies by going to : https://1lib.us/?regionChanged=&redirect=184788137 It is called ZLibrary. Easily download and read on any device. If they lack the proper format you want, just install Calibre software and convert any format into any other. All free.
I justified doing this by thinking of it as a way to create a backup of all (yes, all 5k) of the books I already bought.
