I don’t think FB would invest in creating a statically typed Erlang if they were walking away from it. A lot has happened in between the time period described in the article and the current situation.
In addition, I don’t think FB walking away would shake my faith in the BEAM even a little bit. FB is an opaque structure with its own internal priorities. But this community is not an opaque structure, and has repeatedly demonstrated its resilience and commitment to purpose. If, after hanging around the BEAM for a bit, you don’t trust this community to deliver over the long haul, I don’t know who you could trust.
