Firstly, GA4GH has commercial members as well as academics, and all collaborate together to produce file formats, standards and protocols.

Secondly you missed out a key part of funding - precompetitive alliances. Eg see the Pistoia Alliance (https://www.pistoiaalliance.org/) who funded the SequenceSqueeze project into compression of FASTQ (http://www.sequencesqueeze.org/).

The notion here is simple - there are some technologies that are so core they cross all the commercial and academic boundaries. Collaboration rather than competition is considered to be to the mutual benefit of everyone involved. It is this mind set which lead to the Alliance for Open Media (AOM), who are also in direct competitive with MPEG.
