Just an FYI, I sent a lengthy write up/ business case to the Telerik team to restore the Grid to UI Core (effectively reverse their decision made for 2014 Q2).
I provided examples of how products like Kendo (and their competitors) rise in popularity by being involved/used in major Open Source projects / products like NopCommerce. I also provided dollar amounts they would lose just from me alone (and it was nopcommerce use of them that led me to them to begin with)
I personally have worked with 3 different clients who each acquired a Dev Craft Complete license and have continued to renew (my footprint alone generates them roughly $3600 / year as their Dev Craft Complete was about 1200 / year before they rebranded their product lines). Once NopCommerce migrates away, there is no need for me to have the 3 clients continue to pay for these licenses as it would make sense to invest in its replacement. We use Kendo because nop uses it. Had Nop used DevExpress or something else, then that product would have got the attention. Simply put, Kendo has a lot of competition and they NEED projects like NopCommerce to utilize their product so that they can upsell professional licenses to people like me who leverage more widgets.
To be clear here, every single NopCommerce release, I always apply the latest UI Pro version of Kendo. So in my 3.9 environments, I am presently running 2017.2.504. There are just other features like the Scheduler and listviews that I use for plugins, etc. I am sure there is many others who do this, and Telerik stands to lose a lot of business by their decision once Nop replaces the grid (likely in 4.1)
Anyway, likely nothing will come of my last ditch effort to convince them losing their footprint in a platform that has many thousands of implementation across the globe is not in their best interest.
