Curious what "moloch" means in this context. I can google it, of course, but I get "Biblical name relating to a Canaanite god associated with child sacrifice". Which doesn't help me much. End users are children that Google is sacrificing? Or?
In this context, I would interpret "google's Moloch" along the lines of: Google is net-bad for the world, because of privacy issues and problems with centralisation and so on. Using Google's software (and services) makes them more powerful, so people don't want to use Google's software. But because everyone else is using Google's software, the world is optimized for Google users in a way that it isn't optimized for non-Google users, and so it's difficult to escape. And so Google grows yet stronger, and it becomes more difficult to escape.
(To clarify: this is my interpretation of grandparent's use of the phrase. It's not my own position, and there's a decent chance that I'm completely off-base and it's got nothing to do with grandparent's position either.)
I just read the character description for Moloch in Paradise Lost, and don't see any obvious theme you might tie to Google.
In fact, I'm still not quite sure what the original comment was trying to say. Apart from some fuzzy notion that capitalism is sort of like Moloch and we keep feeding it with our "children". Where children is what? Privacy? Money? Open source tools?
Do you have another hypothesis about what the term means in context? I note that "it's a reference to Paradise Lost" is not very descriptive: for example, if I talked about "Google's Frodo" you might ask what I mean by that, and "he's a character in Lord of the Rings" does not answer the question.
Take a look at, say,

Lots and lots of Moloch. Your hypothesis is 'it's a reference to some logorrheic blogger'. Sure, it's possible you're right but it's one hell of a weirdly specific guess. It's not like the three people to ever mention Moloch were Milton, Ginsberg and internet-man-addicted-to-his-own-typing.
