You raise an interesting perspective to this whole GPL "hijacking" issue that's been going on, and to be honest I didn't think it had much merit before reading this. I can see how, with such a ginormous user base, it's attractive and beneficial for Woocommerce users to take these offers. But the support aspect is a huge side of any tech business, especially ecommerce, and that is where companies like Woo should be putting some focus to generate more revenue.
