That licensing (GPLv2 & commercial) is pretty permissive. It's open-source. They didn't even pick the AGPL, so you probably don't even have to share your source code if you're feeling selfish and running your / your business's own web app. (But seriously, share. Being open source boosts your reputation even if you don't actually care about paying it forward.) (The commercial license doesn't allow private modifications, though it does give a perpetual license. Perhaps it could use some improvement if they want to make more sales. http://www.webtoolkit.eu/wt/license/Wt%20License%20Agreement.pdf http://www.webtoolkit.eu/wt/license/Wt%20License%20Agreement... )
