I was reading https://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux_derivatives today and found the following:
I think the entry about Oracle Linux is undermining very important aspects that can make Oracle Linux a preferred choice over other RHEL derivatives, such as providing most recent patches and errata for free. The reference also points to a very old document from 2008. The statement that it requests personal information, to me sounds very much like requires personal information, which as far as I can tell, isn't the case.
