There are alternatives to each of the Adobe products, self hosted and available offline. People going the Creative Cloud route for their daily job are in a situation where the alternative costed too much or doesn't allow them to do their job in a sufficient way, so there was no real viable options from the start.
The problem is not really to trust Adobe or not. Adobe doesnt have any track record of great online services, I don't think they have an image of high quality software either, they do some amazing things and bring killer features, but I harldy heard anyone being loyal to Adobe itself.
I think this whole discussion would have taken a different turn if it wasn't Adobe but Amazon AWS or Google. When S3 is down, I don't remember seeing more than a few comments in the 'you should have self hosted your data' line. Why is it so different for Adobe ?
