I had an interview where communicated some critics of scrum, some that i agreed with experience and collected through posts about it etc, and was dismissed even without receiving no counterargument during the interview because they were looking some strict believers of scrum, it was an interview with a couple of non tech managers, i guess that’s the issue, scrum is a shallow version of XP who serves non tech middle managers, there is no criticism about it that can be useful to change anything, tech people already knows, but until companies keep useless middle managers around, the tech people just have to accept it
