For me I see Matt as an dog trying to mark what is his and slapping GPL license on top of everything. If so I would like to see some of the woocommerce plugins released publicly as it falls under GPL
WC plugins are 100% GPL. If you take a delivery of a plugin, you get all of the source code, and have all of the freedoms to use / modify etc. as WP itself.
The whole situation with large amounts of "premium" plugins that apparently are GPL for the most part (or at least should be) but don't like to talk about it, include all kinds of license activation features and are split into a separate "free" version with reduced feature set and advertisements splattered all over is a little strange. It's also very off putting when you're used to the typical way open source is developed and distributed.
