The essence is that RedHat bought CoreOS. I didn't realize HN was a place people expected to see purchase prices in headlines.
I think a headline with the price tag would have simply been more useful. I had to spend 30 seconds to find it, and that's the main piece of information I wanted.
Out of curiosity, why "should" that be in the title? There's only so much one can fit in there and, personally, I think the price itself is just fine in the article/press release.
This story is inherently about a purchase and all that needs to be added is "for $250M".
