What that page appears to say is that if you build a web application
with ExtJS and distribute it for others to use then it must be under the
GPL v3 or a similar "open source" license.

If you build an application and put it on your own site, i.e. just *use*
it you wouldn't incur such obligation as far as I can see - since
they're not using the Affero GPL.

I don't see where they consider use on a Web page as "distribution".
However, if that was their intention they should probably have used the
Affero GPL instead.
