Wow, you are a sad, sad man.
What you said was "In daily Scrum meeting only the team and the Scrum Master are allowed by definition."
Which is fairly unequivocal. "By definition" the Scrum is open to observation by any actors outside the time.
Also, in many settings it is not "the team's right" since management and product owner sponsor the process.
Nevertheless in any sensible interpretation of Scrum only the bits that are relevant should be retained. My main issue of the wording is that these things are often taken up literally, even if only at the start. The sole purpose of the daily standup should be to facilitate open and candid communication between team members - it should specifically "not" be a show-and-tell for the the rest of the business.
It's an oldie but a goodie (-:
no, really, you're a super guy. you've convinced me.
Build a system that even a fool can use and only a fool will want to use it.
