I do happen to know the author. He worked in, as I understand it, an MSSQL environment beforehand, but interestingly he didn't mention that either. My guess:

I do happen to know the author. He worked in, as I understand it, an MSSQL environment beforehand, but interestingly he didn't mention that either. My guess: his thinking was MVCC-implementing databases that could fit the category: "an archetypal proprietary RDBMS, an archetypal embedded database, an archetypal document database/'NoSQL'" for some point in time. The people going so far to even hit that page already know about client-server, open source, OLTP SQL databases and maybe even some of their shared techniques. In this list, InnoDB technically should be in the 'embedded database' category. Point being: I think it's awfully assumptive to presume a conspiracy against MySQL, old feuds aside. The world is just very large and this tries to draw a shape around a bigger part of it.
