I think most people object to, argue against, or otherwise resist New Things (...as in - People Do Only 3 Things: Good Habits, Bad Habits & New Things).
Other people bombard us with advice and suggestions about 'better ways' to do things. When we understand "People Do Only 3 Things", it is easy to see how our Bad Habit ruts make it very difficult for us to see value when other people talk about accomplishing New Things.
This is especially true when other people's New Things are grandiose goals. And, of course, regardless of their size New Things face criticism. One person's BHAG is another person's grandiosity...and worse - many small-but-fresh ideas and little innovations face stiff arguments and criticism from those who 'know better'. That's to be expected. There's a lot of entrenched thinking out there.
But...
We can buck that trend.
We can take time to understand other people's thinking.
We can choose to keep our minds open to possibilities.
