I never said Telerik or Infragistics gave up. I said they accelerated their plans to diversify. Look at the date of the first Kendo UI announcement http://www.telerik.com/blogs/kendo-ui/page/65
And as far as I remember they didn’t raise any additional funding to do that. So it was (at least in part) a shift in the strategy to loosen the dependency on .NET control sales. And the resources to do that probably came out of the “.NET budget” or affected it in the future.
