It's an interesting point, but I'm wondering how to unpack it.

"If Twitter was open... a dozen people innovating on it..."

Though not 100% independent of their funding model (loss-aversion bias might lead us to conclude that big companies take less risk), presumably Twitter has at least a dozen people trying to innovate on it?

They may not be doing what [parts of] the community wants, but that's not quite the same thing as not innovating.
