You ever tried to maintain or enhance an ASP form that was built 20 years ago and enhanced by random devs with no documentation? I was working with ASP forms 15 years ago that were hopelessly outdated, included tons of technical debt and were not in the least bit user friendly. You can accomplish so much more with things that ship in every browser now. It’s not a very modern technology and you miss out on things that are now very standardized and much, much easier and quicker to develop and maintain.

Also, Microsoft.
