As a non-business outsider it's even weirder than that, since Gmail is free for regular "consumer" use. It's as if Ford gave away ad-plastered pedal cars for free, but if you pay them for a business car they give you a plain-painted (I just guess paid services are ad-free) car with no wheels or engine. Weird segmentation, and totally unexpected, I can easily understand how OP made this mistake.
