Good article!
I would like to add the radical side of MMP, particularly from the perspective of welcoming newcomers. VASL, TTP, ASLSK, and eASLRB all represent the radical side of MMP; they are never conservative in this regard and actively embrace new technologies and innovations within the community.
Think about MMP's past competitors, Avalanche Press and CH have published systems with potential (PG and ATS) but they are exactly the opposite of MMP. They are aggressive in their release plans, hoping to reprint/rename and empty backlogged inventory to achieve financial balance, even resorting to fraud and false advertising. But they are very conservative in internet marketing, prohibiting Vassal, threatening TPP and fearing that any online reviews could diminish the commercial value of their works, ultimately leading these good systems into a dead end.
