Presumably doing it via the ticketing system is simpler - so why would they use the more controversial & more complex system to do it if the other works?

Of course its possible this is just being draconian or whatever, but if I were a betting man I'd wager they are doing this because it is in some way necessary

Necessary does not imply fair, or correct, or anything. Just that I would be surprised if they are doing it if the simpler alternative works

Well, necessary in the sense that just writing traffic traffics has clearly not gotten cyclists to stop hitting pedestrians.
