So you are saying the clergy in the Roman basilicas were wrong to oppose Urban VIII's reform of the Breviary, particularly the hymns? They weren't censored, since his reform went against the tradition of St. Ambrose and other great Christian hymnists.
What about the opposition from Milan and Toledo respectively from the Pope's attempts to impose the Roman Rite on them? Were they wrong to oppose him?
I would like to see a source which states specifically that the clergy in the Roman Basilica's
refused to obey the Pope in the matter. I do not believe they exist.
There could be many reasons why clergy could have continued with other versions of the breviary, while remaining obedient to the Pope. The Pope allowed older continuous forms to remain, and he may have given indults for other reasons. Also, in those times, copying was very slow, so it may be that clergy may have had to wait some time before adhering to the new law.
There is nothing wrong with voicing your concern to the Pope, but it should be done privately, and always with the understanding that in matters of the sacraments, the prayers of the Church, the laws of the Church, that when the Pope binds the Church on the matter, it is bound.
St. Peter's successor retains the power given to St. Peter. Whatever he binds shall be bound, whatever he loosens shall be loosened.
