I don’t think that qualifies as “nothing happened” when features used in high-profile events fail, with the CEO and a potential future president left on the line. Any other platform wouldn’t have struggled with a stream of this size.
I guess you might say that’s just one thing, and other than the CEO’s live streams not working, everything is fine. But there are numerous other examples of accumulating paper cuts and failures at Twitter. I think this is close to what most of those doomsayers expected would happen.
