Hi Andy,

Yes licensing with ExtJS is complicated. 

Sencha release an Open Source version of ExtJS under GPL v3 and have a FAQ here [1]. It is availabe at this link [2]. Also from this page:

"Sencha’s current GPL policy for Ext JS is that major releases, such as 6.0, 7.0, and the first minor release immediately following a major release, such as 7.0.1, are available under GPL v3. All other releases, such as 6.5 and 6.5.1, are available to commercial license customers with current maintenance and support agreements."

>From [3] - "GeoExt3 is dual licensed. You will normally use it under GPLv3. If you own a Sencha ExtJS Commercial License, you have the right to use GeoExt3 under the BSD License."

The community edition is a commerical license for a company or organization with revenue up to $10,000 per year, so GeoExt in this case could be used under BSD. Premium releases contain additional functionality such as exporting grids to Excel not available in the GPL edition.
