I have some question about GitHub files, I hope it is a proper place to ask.
I downloaded the gravity forms from https://github.com/wp-premium/gravityforms
You may know that the plugin itself is sold by min price 59$/year in its website https://www.gravityforms.com/pricing
I am surprised if it is not free in the original website, how it can be downloaded for free at GitHub?
Do you think I can use the version from GitHub without any stability and safety issues?
