What’s going on with Articles on Microsoft Azure Collective?

This is expected. zcoop98’s comment references a question I asked which addressed essentially the same issue.

SE Inc. actively encourages Collectives to copy-paste their existing documentation and articles into SO Articles.

From an earlier Collectives tour:

Our editor makes publishing content easy – choose the Markdown or WYSIWYG version. If the content exists elsewhere, simply copy and paste and your formatting comes along for the ride.

p.s. there’s more discussion in the comments under my answer to the same question.
