I don't think what has been done here is comparable to other forms of "finding vulnerabilities". Linux and everyone else would be happy if people find vulnerabilities in their code and report them back. And it is not like linux team is unaware of this "vulnerability"

This is more comparable to DDOS ing a web server to test their capabilities of handling DDOS. And they are aware of the issue. And they told you to not do it when you did it before. You just don't waste other people's time/money like that unless they give you the permission.
