There was a segment today, and one yesterday where they actually put Christian on air for a bit longer and he explained things a little better. The one today was definitely obnoxious. But whatever. There's a lot of nuance in why the API decision is annoying and some of it really does boil down to old users feeling betrayed or having diverging preference. I definitely feel betrayed, and have a preference not to be tracked on my semi-anonymous internet forum.
But to someone who hasn't spent a decade+ on Reddit, the argument makes sense I think. The API does represent an opportunity cost. Whether that opportunity cost is grounded in reality, or MBA brain rot is probably outside the scope for All Things Considered
