“Going GPL didn’t change anything about our business.” Adii Pienaar
“we got a lot of flack when we forked Jigoshop
to create WooCommerce” Adii Pienaar
“The GPL gave us the opportunity to contribute to WordPress
core, which is now being used by millions of people.” Adii Pienaar
“It influences the general quality of code within the WordPress
ecosystem, making all products (as a collective) better.” Adii Pienaar
“It forces theme and plugin providers to focus on the
support of their code as the primary way of building a sustainable business.” Adii Pienaar
“It’s not about money; it’s about freedom.” Mark Pilgrim
