2) You have no idea what you're talking about. ADO.NET is arguably the MOST robust database driver abstraction out there, with support for just about any DB.
3) Simply not true. Conservatism strikes everywhere, especially outside of startups. However, it's up to the developers to decide if a technology is viable for their ecosystem, not you. Just because it's new doesn't mean it's better.
4) First-class experience? Tell me how robust your Javascript refactoring workflow is? Python? Oh, that's right, it's damn near impossible to refactor either one without investing serious time wading through code.
5) IT stuff is hard, whether you're running Nginx/Apache on Linux, or IIS on Windows. It's not, however, more difficult for IIS. Technet was outdated anyway. Look at http://www.iis.net/. It's way more useful than Technet ever was. Oh, and you don't like IIS? It's what OWIN was made for. Use whatever server you want, or be like those cool Node kids and use the framework to run the server!
