Parece que no hay problema por su licencia, depende de lo que se quiera hacer:

Licensing Overview

The TwoDesk Component Library is available under two distinct licenses, each based on principles of fair exchange, or quid pro quo ("something for something"). From a licensing point of view, we have two different component library products, although they technically have the same source code. Which one you use will depend on your usage and distribution:
Commercial License

The commercial license allows you to provide commercial software to your customers or to distribute software that uses the TwoDesk Component Library within your organization. This license frees you from the restrictions of the GPL. In a nutshell, if you do not want to comply with the GNU General Public License (GPL), you will need to purchase a commercial license.

Open Source License

If you are developing open source applications, this license allows you to distribute your software under an open source/free software license to all those who wish to use, modify, and distribute it freely. This license allows you to use the component library at no charge, as long as your software and its complete source code is available and freely distributable according to the terms of the GPL. We base our interpretation of the GPL on the Free Software Foundation's Frequently Asked Questions. For more information on the TwoDesk Component Suite Open Source License, click here.

General Licensing Guidelines

If your software is licensed under either the GPL-compatible Free Software License as defined by the Free Software Foundation or approved by OSI, then you should use our open source license.

If you distribute a proprietary application in any way, and you are not licensing and distributing your source code under the GPL, you need to purchase a commercial license.

If you are unsure, we recommend that you buy our cost-effective commercial licenses. That is the safest solution. Licensing questions can be submitted online for our advice, and we encourage you to refer to the Free Software Foundation or a lawyer as appropriate.

Commercially licensed customers are free from the requirement of making their own application open source.

For OEM's, ISVs, corporate, and government users, a commercial license is the proper solution because it releases you from the strict requirements of the GPL license.

You can test the component suite under the GPL license and inspect the source code before you purchase a commercial non-GPL license.
