Sharp: Closing a door

Provided no other adverse outcomes occurred as a result of how this was achieved. It is unlikely that we could e.g. institute a code of conduct on LKML, and a "police force" which can enforce it without also impacting it negatively somehow, e.g. each time this police force steps in and enforces a CoC, it might apply quite mindless set of criteria to determine if CoC is violated followed by a process of escalation that eventually would remove anyone from the kernel development community, up to Linus himself. This is sort of bureaucracy and enforced niceness is always stifling in some sense even if its intentions are good.

> For example: can you demonstrate that testing would result in better software for any given new software without any tests?

Possibly, but writing the tests takes time that would be removed from other development. Maybe the quality is better, but functionality is less.

There is no free lunch. I think these repeated discussions about tone of the LKML are also a harm per se because they are also likely to scare off any new developers because they now expect to be flamed and have their mother and pet dog insulted, regardless of whether this actually would happen to them.
