I can’t say whether the poster you’re responding to actually read the article. However, the article says “…installing buoys along with razor wire…”, so it doesn’t seem clear to me, that the razor wire is necessarily part of the buoy installation. It could be they are installing the buoys, and then also installing razor wire on the banks of the river.

While it is clear that the poster missed the mention of razor wire in the article, jumping to “lazy” or “bad faith” seems like an overreaction.
