Yes, I am saying that you are at vastly less risk of losing your data to an SQLI flaw on Google Mail than you are on some small competitor to Google Mail. I am saying exactly the thing you seem to be surprised I'm saying, and if you ask any 5 other software security practitioners the same question, at least 4 of them will say the same thing (I'd actually be surprised if 5 didn't).
Very well then. Practically speaking I'm much more concerned with spear-phishing on Google services than what we're discussing, but I'm glad you took the time to make your points. I won't hold my breath for them to introduce more flexible plans any time soon though... (As a sidebar, MS Office365 looks to be about the same thing, but not much different than Google on price/plans.)
