If that's the rationale it has to be one of the worst tech product decisions in history. Out-doing even Googles collection of product shutdowns here.

I think it's a lot more likely that there are/were a horde of PMs there who thought it was a very dumb and short-sighted decision to shut it down at the time. In my experience, it's usually some high-ranking exec who makes confounding decisions through authority in big tech. Not so much the average IC PM who has to spend time understanding their users for their job.

Thanks for the reminder. Yes, this was pretty much 100% the rationale from Twitter at the time.

What was your position at Twitter at the time? I'm interested to know where you heard it from, to the extent that you can disclose.
