[wp-hackers] Disabing a paid extension of our plugin if the licence is not renewed, is doing this too agressive?

[Chip Bennett]

Main Plugin, extensions, whatever. If you're disabling *functionality*,
then you're restricting *use*, which is GPL-incompatible.

You can disable access to updates and/or support (see Mika's previous
email) and remain GPL-compatible. But you cannot restrict *usage* if you
wish to remain GPL-compatible.
