Oracle/MySQL isn’t really an analogy. Oracle owns MySQL; Zend doesn’t own PHP. But what about the Zend engine? Is that 100% open source, no strings attached?
From the Zend site:
“Zend is committed to continuing its investments in the PHP community by both contributing directly to the core technologies and by help maintain and grow the vibrant ecosystem PHP enjoys today.”
Will Rogue Wave take the same position? If not, could another entity take over the engine?
