Yes, some people go over the top with decorations...I don't mind because it makes them happy.
For example......
Our next door neighbor (now decorating for everyone in heaven) had so many lights on his house, BWI airport used it as a landing beacon ---- well, maybe not but it was beginning to remind me of Osborne Lights.
It WAS colorful and people stopped to look.
When you remembered as a child his father would not allow ANY recognition of any holiday, it was easier to enjoy the lights with him.
I have not seen anything offensive at WDW.....so I say...let them have their fun!
