Although I agree completely with your statement, especially wrt right to repair and DRM, I don't know what you would want the government to do in this case to protect a person's data when they choose to store it on a free service that offers no guarantees of anything, and specifically states in their TOS that they may remove an account for any reason at any time.
On top of that, this person chose not to take the simple step of using Google Takeout to back up the years of data that he couldn't afford to lose. If my business or mental health depended on that data, I'd be doing that every couple of weeks at least.
I do think it would be nice if Google would, when they remove an account, give you a couple of days to go to Takeout and download the data.
Just deleting it with no warning seems very rude indeed, especially when you consider the amount of advertising revenue they generate from serving people's data.
Google should also make less claims about, "A safe place to store your data"!, if they continue to remove people's data without warning or recourse.
