Us RFF fans (well, most of us at least) won't quit the show until it lasts, whatever stupid twists CBS comes up with.
But I doubt the FB casuals will be happy. I'm pretty sure they won't be.
Even before this recent social media season they were spamming "geo back to normal people", "why do they all look like models", "give average Americans a chance" and they definitely didn't support the Blind Date twist in S26.
Prepare for an uproar, though there's still a lot of time until the official announcement. (Unless it's a public start, which I have no idea about.)
