British English has many phrases for complaining about a change while going along with it.
Here we go again: Another change has been announced, and it will be no better than the last one.
Typical: This was bound to go wrong.
What was wrong with the old one?: I do not see why this had to change.
Don’t get me started: I have complaints, and I am about to share them.
To have a good moan: To complain at length and feel better for it.
