Unfortunately this kind of moves from different companies affect the entire SaaS space.

There has always been a degree of uncertainty when committing your business to one service like this... what if they increase the prices? what if they will close? what if they turn bad and close my data behind a payed wall? will they be able to keep the service up most of the time (just think of the time when Gmail went down..)? And so on...

This is only going to make this worries a bigger issue when choosing to commit to one of these services.
