I got fired from any last job after being one of the only engineers willing to say something to management about this. I figured I had a popular opinion - many other engineers often DM'ed me on slack encouraging me to continue speak out, including my own manager, so I somehow figured I should be safe speaking out, politely, as a respected majority representative.
In fact I was dead wrong. By saying that scrum was a problem, I ended up making product managers / CTO who loved scrum and used it as an hour long opportunity to lecture the team every day feel threatened.
Getting fired was one of the best things that ever happened to my career, because in retrospect it was a dead end company that was run by fear. Management was afraid of ideas or challenge to power to the point where innovative ideas and feedback were never well received and a culture of fear and not stepping out of line arose, even though it was sugar coated with fake company values of "openness" that nobody really believed in but that managers loved as a way to elevate themselves.
I suspect many companies are a my least a little bit like this. Unfortunately it is human nature and there are so many stories in history, usually of narcissistic dictators, that mirror this.
This was a very extreme example but I'm sure many other companies struggle with this when it comes to challenging scrum. Managers tend to love scrum because it's a chance, daily, to "manage" and to get status updates so that they feel comforted. It makes it so that trust is no longer necessary, and bad managers are often bad at trust.
I guess another way to view scrum is to realize that it is often a reflection on management's subtle fears and insecurities being projected onto the processes of the company. It is an instance where employees unfortunately must manage up.
