Broom Mount

Why has the broom mount duration been changed, what purpose does it serve to take them now?

I have very much enjoyed using mine and I know a lot of other people have as well.

It is not as if I expected to keep it forever but I did expect to be able to use it for the length of the original duration. It seems a little unfair to put out an item and then change it so drastically and give no explanation for that change.
