Twitter test-launching ephemeral tweets called Fleets

I really don't get it. Twitter has five thousand full-time employees. I have to assume at least 20% of them are in product development in some capacity. What exactly are these people doing all day?

I can't point to a single notable product innovation they've had in years. And they continue to ignore the drumbeat of user asking for an edit button, and are completely unable to come up with any kind of reasonable solution to the abuse or bot problems.

I don't know Kayvon personally, but what exactly is wrong with Twitter that it's so bad and slow at product development?

So Fleets can be used to send deniable abusive messages ?
