Raven 11, well done mate, the only error you are doing is in assuming that you are being criticized by junior crew only...no mate there are a lot of B scale captains that are equally put off by this whole debacle.
The fact that you say that you would not have joined on B scales is probably correct, but the fact of the matter is that quite a few guys are more than happy to extend on B scales. They have even chosen to train within 2 weeks of retirement,after being a line pilot for 20 years and telling us all on how he cannot wait to leave this Sh1t company and on how he is counting rosters.
I'm sorry mate but a lot of "Senior Pilots" are making your argument loose impact
