I really think the author is missing out here - for the sake of just sticking with what they know and not wanting to do any actual research, it's impossible to come up with an actual objective choice. So misinformed, I get that .NET/C# development is not everybody's cup of tea but I think it's crazy to title an article "Choosing a Web Framework/Language Combo for the Next Decade" without even evaluating an extremely popular option due to simple disinterest. The lawyer comment is just irrational fear (and I get is probably meant to be a bit of a gibe towards Microsoft's licensing schemes), unless you're writing something completely from scratch, you need to be aware of the licenses of ANY library/framework you depend on, even if they're free.
