Except...
I'm scared when I think about VC money here. One day someone is going to want a return on that investment and not sure how that will play out.
Imagine if ncurses decide to charge a license fee out of the blue...
Or perhaps more likely in this scenario, one day the framework stops getting updated, then gets rebranded as the community edition, and no longer receives important and/or timely updates.
I'm all for developers making an excellent living, just need to know my own risk factors when investing in tooling and frameworks, etc. It's hard to know here what the future will bring.
Then again, there is no really compelling alternative to this most awesome creation!
