The call to action of the article below is reasonable. It encourages those without licenses not to modify scaffolding.
However the coincidence of events (falls for example) and some feature of the events (moderations by non-licensed people) is only actually a way to tell a story. It does not prove the connection. We don’t know that the licensed people would have done anything different.
Are they any mishaps to report on scaffolding that was entirely under the supervision of licensed people? I expect that there are many such incidents.
