Disagree with premise. “Reddit going dark means you can’t find anything useful on Reddit.” That’s the real headline.
You’ve been using Google to search Reddit. There was even an article here last year (or whenever) about how to improve your search results by using Google’s site: command to search Reddit, “since that where all your answers come from anyway.” That’s not really “using Google”, and Reddit going dark has nothing to do with Google at all.
It’s like the old joke of losing your car keys, but looking for them under a street lamp, because that’s where the light is. When the street lamp turns off or burns out, sure, there’s no light, but that doesn’t mean your car keys were there anyway.
