What's really sad about this is that they had to give up Leaf because the whole thing was VC-backed. Commercial support is a huge part of open source software's viability.

I applaud their decision to pivot and shift their focus elsewhere to win. That said, the irony is too great for me not to mention: open sourcing is now recognized as a hugely democratizing force in the software world to upend commercial giants, yet it's commercial giants that can afford to invest in the long run and support open source projects (so that they can increase the sphere of their influence).
