The idea of storing sensitive data at one of the most data hungry company in the world "for security", doesn't sound like it came from a genius. I thought I was pretty clear earlier?
Moving FOSS into the cloud as a SaS sounds kinda regressive to me...
If you can explain your fears perhaps we would understand, because I still don't know why using Azure is a privacy trade? Does Microsoft "steal" the data?
It happens all the time, and also; when using proprietary software you never know, and that's the big issue (for me). I never use SaS or MS-products (I only use FOSS) so I don't fear for myself.
Not agreeing with thread OP here, but I would certainly differentiate between "stealing" and "exploiting" (not in a security exploit sense). User data certainly gets exploited on _some_ SaaSs that would otherwise be unexploitable on your own stack.
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.
The question was about Microsoft, and it depends on the definition of "stealing" and the definition of "your". It's in the terms and conditions when using their services. As a user you agree to a lot, that you probably wouldn't agree to if you took your time to read the fine print. Many SaaS operators has also a history of selling data to others, and a breach of the service might effect all users of that service and not just one. Many companies have restrictions against usage of SaaS for exactly those reasons...
Next time when I have access to a PC I can do the searching and reading for you, but until then you will have to wait. I will have access to a PC in about 10 days. I'm not great at typing without a keyboard. But if you can't wait, just search it on the web. I'm sure HN is full of articles about Microsoft and privacy issues as well.
