Again - Dalamud was not a project that received heavy support within Garlemald itself. Nael van Darnus was very much acting against Garlemald's interests. So, too, was Zenos - who admitted to never really caring for his father's cause and simply wanted a good fight. Nothing else mattered to him.
It's no different to the real world. A war may be started by politicians and military leaders that causes strife elsewhere but the people living within the country responsible are largely without blame. Many people - with various degrees of influence - speak out against them though find their hands tied. Then there's the issue of misunderstandings and rogue elements coming into play...but I digress.
As for stifling festivals? It's mostly a precaution - and it's no different to how Ishgard chose to operate when it came to anything even suspected of being associated with Nidhogg's brood. Some may very well be harmless yet other practices may not be.
In short, Garlemald is fairly divided in terms of its approach to many of the more controversial decisions and projects.
