To be fair to Martin Fowler, his writing is generally more journalistic in its approach. Unlike the others you refer to, who are very ideological in their writing, Fowler describes technologies and programming patterns/approaches, in much the same way a tech journalist would do so. And he writes with a level of detail that suggests he's done some significant coding. Also, re: open source, he does sometimes write about particular open source projects that have successfully made use of the tools or technologies he advocates. Or simply about the open source projects themselves. I happen to enjoy a lot of Fowler's blog writing. In particular, I've enjoyed reading his posts on the LMAX architecture. Fascinating stuff.
