I think it's clear that each individual team makes what is a rational decision for their product; the problem is that when Google are also a browser vendor (and it's almost always only Google's browser that the initial launch supports) then it's very easy to walk away from this viewing Google as malicious. One launch that was Chrome only would look kinda shitty, several dozen just looks like malice: the probability of such consistent behaviour is incredibly small (if we say the probability of cross-browser support is 0.99, given most sites on the web are, then the probability of a dozen sites all being cross-browser is 0.89, and the probability of none of them is 1×10^-24). It's incredibly unlikely that multiple unrelated web development teams would all decide to go for Chrome-only, and that's reflected by how few non-Google sites are Chrome-only (i.e., the optics would be very different if there were large number of major web launches that were Chrome-only from companies that aren't Google). As such, if Google did actually care about the web and interoperability (given the Chrome team spend a lot of time talking about and working on it!), one would reasonably expect Google engineers would spend more time trying to report bugs in other browsers (because plenty of them aren't that hard to track down) rather than other browser vendors spending a few days fixing all the bugs after launch and then often spending several months trying to get it officially supported (and often being told "it still fails tests" with no further information (see previous point about caring about interop) while nobody else can find anything broken). In reality knowing many people at Google, yes, I think I can say it's Google having no cohesive whole and acting like a million discrete teams with no over-arching goals, each wanting to launch their MVP ASAP by caring about a single platform, but it sure as hell doesn't look good.
