Here's a question that is about the same topic as the one I want to ask: Is Telerik Extensions for ASP. NET MVC Free?
Its answer is outdated — at least, the license explanation on the vendor site changed — and I have several more aspects to ask about that are not mentioned in either the answer or the question.
Should I create new question, or write an edit for the old one (the old one is not mine)? I once lost a lot of reputation after making the wrong choice in a situation like this, and would like to avoid having that happen again.
