No matter what the intentions are on either side, this is still a user creating data inside the black box that is a web service/company/database and once you do that it's their data. They can shut you out at any moment for any reason, right or wrong. I try to avoid all of this where possible and if I have anything in the cloud I keep a backup of everything, say in the case of Fastmail or Gmail I use isync. Anything else that isn't critical I just accept that one day it might not be there. I know this isn't addressing anything in the article directly I just mean generally if people are going to be annoyed if a company has changed the goal posts in their domain then don't commit to using that service. Offline first!
