This would be true if it were an area where Open software didn't already dominate. As others, including the developers of Metor, have stated, this software being GPLed was detrimental to the overall user base because there were many people who were not willing to use and contribute to software with a restrictive copyright. The existing culture of web development is already centered around permissive licenses, trying to introduce a new product with more onerous usage conditions now will just lead to it languishing because its usage of the GPL is a weakness.
