> I think in general it’s not a good idea to use free services for businesses, but in my mind it means that Google makes pretty big changes and don’t care if it disrupts you. Microsoft doesn’t do this or rarely does. If anything they start high and drop. Starting free and climbing is not good.

Wow, I could not have stated it better myself. AWS is also like Microsoft in that they start high and commit to only dropping price. They also seem to do a pretty good job at customer service which Google has a reputation for lacking (although that is Amazon's bread and butter).
