And your solution, "they could have put words to action and made those minis but then they would have had to risk their own money and it would have required effort", while technically correct, is also disingenuous. You do realize there are economic barriers to entry to creating such a startup, right? In all likelihood, it far more economically efficient to ask a minis company to expand their product line than to launch a completely new company to produce minority-only minis as their core product. M.O.M. would likely fail as an independent company.

mainly because, I think, some of them are just as lazy about it as the companies are
