From my reading of the article, you're conflating two seperate events, perhaps due to knowledge of additional facts it doesn't contain, or conjecture, or misreading - it isn't clear.
The blog was shuttered, yes, but on his opinion column he just mentions an increase in editorial oversight and getting notes. You call this "consolidating their opinion content" - can you share details? Otherwise it sounds mostly like an euphemism for "they adopted a stronger (guide)line", which is what the piece seems to bemoan.
