> I mean, that's true, but in a not-especially-deep way that doesn't really help or address the issue at hand.
I'm not sure you go the point. If someone's complain is that others can also edit wikipedia articles, they are complaining about the fundamental nature and purpose of a wiki. Don't you understand how fundamentally flawed is the concept of conplaining that others just like you can also edit wikipedia? Those damned editors.
> Why do we have this thing where different people can edit it?
Yes, others can edit it, including your own changes. That is the whole concept of a wiki. Whining that others also edited a wiki shows a fundamental failure to understand what a wiki is and how it's designed and expected to work.
> So, while yes, anyone can edit, some of that gets in the way of the actual purpose, in that "five whys" sense.
No. Anyone can edit it as they see fit. The whole concept of a wiki is a consensus-based process that concurrent changes converge to a stable point accepted by the community. Expecting that your edit should be set in stone while you reserve your right to edit other people's work is simply absurd.
That's why it's important to clarify what an editor really is (not a figure of authority, but a guy just like you) and why it's absurd to be offended and feel entitled to edit over everyone's work but not have your own contributions edited. That's not what a wiki is, nor is it why the concept is a huge success.
> It's a bit like saying, when someone brings up spam (...)
That's an amusing remark, because to me you're actually arguing in favor and in defense of spammers, as they are the ones complaining that their abusive misuse of a system should not be prevented, criticised or fought by the community.
