Probably the biggest disservice done by Scrum was changing our thinking and language around methodology. It made it so that if something was going to displace it, it had to start with a capital letter, be a "real" version of something, and have a lot of institutional momentum behind it. It acted like some kind of social exploit--one we had no immunity to.
So, we ended up stuck with it, suffering untold millions of hours wasted in useless meetings and untold creativity crushed since it didn't fit into the process. We should've just tossed the notion that there's some kind of planning structure that makes sense across all possible projects, then done whatever made sense for our specific environments, not put a name on it, or even talked about "methodology" much at all.
This was Scrum's greatest hack - the whole idea of a prescriptive methodology is anathema to agility. As soon as a process solidifies, all exploitable niches will be exploited to the detriment of the system itself.
I don't get how endless meetings are related to scrum. This is just poor management, which happened before scrum too.
Agile instead of agile, Scrum, Kanban, Scrumban, “shift left”, etc are all words that indicate the place has not only drank the kool aid but tried to drown any voices of reason with it.
