I'm not saying this necessarily applies to compute engines or storage as a service or whatever, but something like gmail (SaaS) where your data is used to target ads at you could be considered exploiting your data. I would not put it beyond large companies to start considering doing the same on their storage-as-a-service offerings soon enough.
If Google, Microsoft or other companies start to look at the data to exploit it hey will lose trust, the customers and the data.
The it will be easy to point to those terms in Azure service.
> SaaS operators has also a history of selling data to others,
Then it willbe easy to link to news about those SASS operators selling the data.
> Many companies have restrictions against usage of SaaS for exactly those reasons...
Then it will be easy to bring examples of those companies with restrictions.
Also, Azure has the best suite of compliance\certifications that demonstrated their commitments.
BTW, Have you read the terms and conditions before speculating on them?
