You could argue against creating the feature, but once it already exists and it's not taking up any real processing power or cluttering the interface, why would you ever remove any feature. Does he understand it? No. Do some people use it and find it beneficial? Probably, yeah. Are you forced to use it? No. So what's the problem?

It's like a car manufacturer ordering a recall to remove the the mirror on the passenger side visor because he never uses it. Some people do, my dude, it's not hurting anything, and it will actually cost you money to remove it instead of leaving it. Just leave it alone, dude.

Or... he's not being honest and he wants to remove it because it hurts his ego to know that so many block his account. Yeah, it's probably that.
