How do you handle a Wikipedia page being locked or semi-protected?

Wikipedia protects articles when they have been subject to repeated vandalism or edit warring. Semi-protection blocks edits from unregistered users and very new accounts but leaves the page editable by anyone with a few days of edit history. Full protection limits edits to administrators only and is used during active disputes. In every protection scenario, the Talk page remains open and the edit-request workflow continues to function: a disclosed-COI editor proposes a change with sources on Talk, an uninvolved community editor or administrator evaluates it, and if accepted the change is implemented through the protection. Protection is sometimes the friend of disclosed-COI work because it shuts down hostile or low-quality edits that would otherwise need to be contested case by case.
