FSL is better than strait proprietary and if a company had to choose between the two I hope they choose FSL. All that said it just doesn’t feel like there is a real hope here for the eventual Open source fork here. It’s just a fail safe for people still on legacy systems and even then 2 years of potentially no new updates … Could be killer for security flaws. With tons of paradigm shifts between then too.
It almost needs a SLA that says if it isn’t maintained to a certain level then it is also opensourced.
