One of us does not get it

Raphaël, I'm not sure you understood.

The solution is to get rid of all of DSA (and maybe anyone that supports them). Removing one side of a power struggle may win you some short term gains, but may be a no-op or even more harmful in the long run. Such a solution is indicative of what I would call an overly-practical mindset, the kind I'd expect from Project Scud.

You can say that DSA's inadequacies and ineptitude are due to specific individuals, but it is a team: each member is free to quit at any time (unless there is some kind of sinister blackmail or other means of coercion in progress, in which case I'm sure we would all appreciate if you exposed it), and each member is responsible for the performance of the team.

If you accept that each team member is responsible, and you acknowledge that DSA's behavior is unacceptable, then how can you imagine that adding or subtracting members piecemeal will effect anything substantial?
