"Probably more the former..."
Google's whole business strategy is built up from leaning on it's monopoly in other areas to force more of it's products down people's throats - these days, I can't seem to get more than a couple of videos on Youtube before an ad (uninterruptable, natch) for Stadia, or G-Suite, or some other Google offering gets foisted on me.
And then, of course, there's how Chrome became the number one browser: yes, to us in the tech/dev sphere, it was functionally "better" than the competition at the time, but I'm willing to bet that it was the great big "download our browser" button on all the search pages that did it for the masses...
... okay, so it's not as bad as the whole Windows/IE tying thing, but it's close...
