Typical human psychology/behavior:
No changes: "This is boring why don't you do something to make it better?"
Changes: "This isn't identical to what I had before so I hate it!"
Even with Minecraft, where you're not forced into changes and can just use whatever version you happen to prefer, people still complain because sticking with their favorite version knocks them into the first category and so far nobody's figured out how to make changes while simultaneously keeping everything exactly the same, in Minecraft or elsewhere.
Basically, people just like to complain (myself included of course!)
You are basically forced. Considering some of the bugs in past versions that were corrected in later ones...
