> To me, Scrum has always been something of a paradox. The whole point of agile is to adapt the process to the team's needs - if you're doing dogmatic agile, you're not actually doing agile.

It seems to me that Scrum has "no true Scotsman" built right in to the model. If you criticize it, a Scrum practitioner can just reply "well, just adapt it to your needs then". Or if you hear of something too crazy a team is doing with Scrum because they adapted "well, they're not doing Scrum right".
