We have some data from real-time tracking that the "vertical speed was unstable after take off" [1]. And that both crashes are similar in that regard, and both accidents could be explained by a problem with the newly deployed MCAS software system.

Clearly, there are no answers yet. There is no known cause for this recent crash yet. But there is some evidence. And that scant evidence might be coincidence, but it also has well-informed people concerned.
