Auto companies that do this are essentialy motor engine companies. At their core, the structure is aligned to the R&D and supply chain required to build a complex machine with thousands of small parts. BEVs threaten this model, as the components are much simpler and require a different organizational structure. Hydrogen engines, in contrast, do not (or to a much lesser extend) so the relevant actors are more inclined to push this idea.
