Nobody owns science, some do own evolution and there is a difference. Will does imply ownership and that demonstrates what the gods of knowledge call ignorance.
There is a science establishment. that has been true since Newton and the Royal Academy. More importantly, there are centuries of experience with quacks attempting to invade science.
The accomplishments of science are so impressive and undeniable that all sorts of wannabes try to attach themselves to science hoping to acquire some of science's luster. It's the best scam going.
When you say no one owns science, you are correct, but everyone involved in science recognizes attempts that lack the commitment to empiricism.
