Overall openwashing is a good thing.
... regardless of how we may feel about the practice.
One of the major outstanding problems with todays technology is the closed-source code driving pieces from individual chips to complex mechanical systems.
Simply having the code visible publicly allows the technology using it to be maintained in the long term. Perhapse commercially from what started as openwashed code. Perhapse replaced by properly FOSS projects later down the line after the commercial support evaporates.
As our world gets ever more mechanised by the IoT trends this openwashing behaviour plays a vital role in sustainability.
