I think it's a bit misleading. jQueryMobile is an official part of jQuery as is jQuery UI, and validation while considered a plugin is ostensibly "official" as the author is a jQueryUI core committer. So while Kendo might be operating under one GPL licensed roof, in the end if you consider all "Official" jQuery projects as one project, they offer a lot more and a MIT license! I know you mentioned those projects as "See etc." but in my mind at least, it's just a question of marketing semantics of what should be considered one project.

That's a fair point. jQuery, jQueryUI, and jQuery Mobile are all very much under the same roof.

The plug-ins are a different story. Some are more "official-ish" than others. So a developer using only jQueryUI must research, find, and add these to a project to "build out" a complete starting point.

We're trying to save developers that time, and provide an unified library that's simpler to learn, maintain, and upgrade. I think it's more than semantics, and when you compare performance, you should also see it's more than just features.

Hope that helps.
