"FOSS won so decisively on the supply side" because it's basically giving away something that would ordinarily cost money. Anyone can "win" by giving away something of value away for free; it's not a victory that's worth anything.

What those adopters are not doing is opening their own source code as FOSS or contributing back to FOSS. That means that there isn't a path to future success.
