ChromeOS encourages you to store files using Google Drive. There is the threat of Google being compromised, yes, even though they take security much more seriously than the average company. More likely, your own account can be hacked, since it's out there on the web and not all developers are security-minded, sadly. But there's also the concern that you can have your Google account shut down and it may be difficult to get it restored.

I would also like to better understand what profiling data Google collects during ordinary usage of ChromeOS. I'm not an expert on that subject and don't want to spread FUD, but when you're logged into the Chrome browser, Google finds out an awful lot about you through your web habits.

Assuming you install updates from your OS vendor regularly, than Microsoft or Apple getting hacked is game over anyway. Google has some if the best tools available for securing your account (very solid 2fa if you set it up right)
