Yup, this guy sets up a total strawman which doesn't accurately describe how I've seen Scrum run at two major telecom software companies. We change mid-sprint

Yup, this guy sets up a total strawman which doesn't accurately describe how I've seen Scrum run at two major telecom software companies. We change mid-sprint (when we need to), we don't have non-programmers running scrums or writing user stories and if you don't complete a story in a sprint then you roll it over to the next one. If you have deadlines and contractual commitments to meet his suggestion of "use Kanban" strikes me as somewhat absurd. Running a team off of a Kanban board has its place (some of our support / platform teams use it) but I'm pretty sure your business owners want a better answer for when something is going to be delivered than 'when my Kanban board is empty'.
