Poll style question have long been made "Community Wiki" on our sites. Note that the [dev-tip] questions changed were all of the form "Post your solution to X," a poll question. We had let this slide in the past, but the recent rash of (I'm sure, innocuous) posts brought the issue back to the forefront.
Furthermore, there's already a place for your [library] docs... the [library] question.
Consider it a policy, posting example code not in response to an explicit question should be Community Wiki. Answering a question, posting an [app] or [library], suggesting a feature, or similar should remain "owned."
This is the policy.
It is totally in harmony with the way all the other sites are moderated.
If you do not or cannot agree with this policy, then perhaps this particular community is not the right place for you.
