Glenn FleishmanI just figured out why Elon Musk pulled the plug abruptly on third-party Twitter apps. It’s an experiment. He’s not communicatinganything he’s doing for that reason. He’s looking at metrics to see if killing third-party apps' access to the API results in a reduction in usage and engagement that makes him think he should re-enable it, and then issue a false apology or whatever.

@glennf I think you’re giving him too much credit.
@rjeitani It’s the worst reason for this to happen, so likely accurate. Some third-party clients can still access the API, thus it appears like blocking and no an API failure. Occam’s Stupid Razor.
@glennf Oh, I have no doubt he did this intentionally, I just don’t think it’s an experiment or anything with more than 5 seconds of thought behind it.
