That's just the release manager asking for help with getting the release out. The wording also strikes me as fairly playful (it's a maritime reference!) so I fail to see how that's "fully corporate" or makes python "formerly open".
This isn't a literal "I am your boss, you MUST work now", this is "hey, I'm the person who volunteered to get this release out, please help if you can!".
