As for more Toolbox-oriented devices, those are often a (rather whacky...) collection of either stolen intellectual property of large manufacturers, other Devs, leaked stuff etc. making it quite hard to play the rules right in terms of settign up a real repo with licence and attracting devs. Gray area market just seems to work out too well for most teams.
But I agree on the disappointment of yours to this fact... |
