2) People who use Microsoft's proprietary technology stack, and then get annoyed at products that fail to interoperate with it seamlessly, despite the fact that it's undocumented, proprietary, and notoriously difficult to interoperate with successfully.
There are very few people who use MS stack and don't get annoyed at interoperability concerns, because those people realize that the fault lies with Microsoft, and stop using Microsoft's stack.
My point is that we're citably competent all the way through.
