Because people have come to rely on it. And no one is suggesting that they run it for free - they could easily charge a few bucks per year, cover their administrative overhead, and keep their foot in this space, while a) not losing money, and b) not losing trust from people who may want to adopt other google tech in the future.

I've still got gmail as an email which I use a lot, but would be extremely hesitant to ever trust them with anything else (I've also got other email I manage on my own). When the sands shift in a few years and gmail doesn't make sense for them any more, they may easily just shut it down, or severely limit it.

Google Business stuff? Would not use it. Google Checkout? I use it, and their tools have not developed at all in the past few years. Google Voice? They have to be losing money on the phone numbers, and I will not be surprised one bit if they shut it off in the next couple years. And people will whine/complain about that too, but the writing's been on the wall for a while - don't trust businesses that you don't pay money to (and don't trust a business to be around just because you pay them either, but it's a start).
