The mods mainly were protesting because they relied on these tools. Reddit responded by making exceptions for these tools, and threw in exceptions for accessibility-focused tools to boot. (Taking the "think of the blind and deaf people" argument off the table.)
The only people that are still upset are the people who just want to continue to use ad-free readers, without paying money.
Reddit is a digital drug dealer that just raised prices on its addicts. The power users you describe are the least likely to delete their accounts and leave. Their rage over something relatively trivial is just a testament to their addiction.
