Can I use ExtJs without License like JQuery?

Question

Can I use ExtJs without License like JQuery? Can I publish website using ExtJS without any permission from them?

Answer 1

ExtJS GPL Licence means that if you are using ExtJS under GPL Licence, and not modifying ExtJS itself, then you are Free to use ExtJS in whatever manner on any Website. But if you take ExtJS and start modifying ExtJS itself ( to make some better 'Super-Duper-ExtJS' Library ), then you have to share that with everyone, because if you start selling 'Super-Duper-ExtJS' to your Clients, then whats going to happen is that 'ExtJS-Company' finds itself Competing with Itself. I dont think you need to share your 'Website's Source-code' in any case. If you need to share your 'Websites source-code' ifself with other People while using ExtJS-GPL, then only the ExtJS-GPL Licence would start looking absurd, and you need to start looking at jQueryUI or DOJO ! But I dont think that 'ExtJS-Company' means to share your Websites-source just for the reason that you used their ExtJS Library ! What say .......
