Based just on what's in this post and not knowing much history about it, I'm where you are right now too. If their concern is "tankie" includes unobjectionable stuff, we can at least give them the opportunity to give us some examples to make their point. If they can come up with stuff that we agree often gets the "tankie" label applied to it but is actually consistent with this instance's core principles, then we should hear them out. But if they are like "well, CCP is actually based," then no thanks.
Your version reminds me of Vonnegut's that was something like this in an imagined conversation with Mary Shelly: "Dr. R - Does it bother you when people call the monster in the book 'Frankenstein'? MS - Not really. There were two monsters in the book, after all, and one of them was named 'Frankenstein.'"
Interesting follow-up to this - Reddit locked me out of the main account I've been using for the past 2-3 years a week or so ago. It had been my totally normal, all over the site account with lots comments etc. The only out of the ordinary thing I did in the couple of days leading up to the lockout was call out what I thought was an AI bot arguing with me about the subreddit blackouts and wonder whether new Reddit was just going to be essentially what your link says. It's the last comment that account will ever make I guess...
Yeah, I'm wondering if the chorus of comments are also harvested from the various prior threads to make it look like what real conversations would be about.
