You're not the only one that complained so far. A fair amount of people don't like the sidebar module, and complaining about it here won't do anything. You could try moving your complaints to Special:Contact/feedback but they probably heard enough complaints of that kind and it wouldn't change anything.

Why not use whatever you found to remove it only for yourself, if you can't remove it site-widely?
