Even Apple had a horse in the race with Color, but once Resolve became free or ridiculously cheap it was game over.. even for more advanced tools like Lustre (which merged into Flame), Film Light, Base Light, Scratch, etc. More than I can count which died even before that.
Turns out if you can afford to give your tool to wide audience with no budget, that's what they'll use (especially if it's any good) and will end up turning to you eventually for more professional setups once / if they get into pro waters.
