The press loves a David and Goliath story; the young disruptor versus the stodgy disrupted.[1] At that time, Dropbox was David, coming out of nowhere in a hurry and had a product that seemingly should be so obvious for Google to launch but hadn't - making Google seem antiquated and slow.
Fast forward a couple of years (aka a decade) and Dropbox is still going ok but Google Drive is by far more ubiquitous.
I guess only time will tell.

Which is perhaps why Google didn't really focus on creating a Dropbox like product until it was forced to because the more long term profitable for Google was a solution/vision based around a cloud first experience.
Not as mission critical as the desktop app, but still pretty frustrating that they can't handle this core functionality after years and millions spent on other bells and whistles.
The "at most a few years from profitability" after a period of what, 15 boom years?, doesn't sound that great as the 3rd place contender.
Also the comparison is between Google versus Dropbox (the underdog David that's analogous to OpenAI), not Google versus Amazon or even Google versus Microsoft.
Google is 51% of office productivity software market versus Microsoft. Microsoft is at 47%, Dropbox isn't even listed. [1]
Dropbox has a decent share of the personal cloud storage market but has really failed to expand beyond that vertical or become significantly profitable. [2]
