Ditto what John Baker said, but l have rarely seen any organization explain the changes to their policy or future contracts. They just send the new version and it is up to the recipient to review and agree to the new version.
By the way, did you ever even read the previous version? I expect that most people didn't.
If you agree with the changes, you don't need to do anything. If within 4 weeks of
receiving this email you do not contact us and disagree with this policy update we
will assume that you take no issue with it. If you do not wish to continue to use
MAGIX Online World due to these amendments please write to MAGIX Online Services GmbH, c/o MAGIX AG, Customer Care, Borsigstr. 24, 32312 Lübbecke, Germany. Alternatively you can send a fax to +49 5741 310 768.
What more do you want? Just read the thing and disagree if you don't like it. Do you think that Google goes to this much trouble? No you get a choice agree or disagree. If you disagree, then you are done with that service.
Stop whining and complaining, and recognize this a the great support that this company provides.
post-update - I offerthis example as a response to "no software company" ever points out chagnes - Apparently Dropbox didn't read your post. They just sent a lengthy email detailing the changes in their policies...how quaint.
