I don't know that the later 'old' Azamara would have behaved differently.
The most galling thing about this is that, should you cancel and lose financially (for flights, hotels etc that you cannot cancel without penalty), your insurers will argue that it is your choice to cancel, because the cruise line has not cancelled.
For this very reason Azamara has cost me over £5,000 for two significantly-changed itineraries. Admittedly for the first (about 6 years ago), I was able to recoup a small amount, but could have lost much, much more.
Better that they cancel, but offer the chance to re-book. They steadfastly refuse to do so.
