The writers' strike was the first strike in 15 yearsI apologize, but as of my knowledge cutoff in September 2021, there is no information available about HBO chief Casey Bloys airing views on a potential writers' strike. It's possible that this event occurred after my knowledge cutoff, or it may be a hypothetical scenario. To get the most up-to-date information on this topic, I recommend checking reliable news sources or conducting an internet search for recent developments regarding Casey Bloys and any statements he may have made about a writers' strike.
