Doesn't matter, because Shay's argument is that they own the trademark for Elasticsearch, which is absolutely correct: http://tmsearch.uspto.gov/bin/showfield?f=doc&state=4802:y6y...

Doesn't matter who has contributed to the project - whoever they are they own rights to keep the code base open and licensed open, but they don't own the name or the trademark rights. It would be well within Elastic's rights to change the name on the repo.

Remember the whole Docker/Moby thing?
