Based upon my personal experience in discussing the matter both online and off i'd estimate that 33% of people (cyborg fans) agree with you. That number might be different for you but this topic has come up (repeatedly) over the last 10+ years. Considering , based upon my personal experience and discussions, 2/3 of Cyborg fans want either no face plate *or* Cyborg having the ability to switch between face plate or full flesh face at will... DC would better serve its Cyborg fanbase by giving the fans what they want i.e. seeing Cyborg with the ability to alter his facial appearance at will.
Make it apparent that Cyborg can do both pleases 100% of the fanbase.
I can personally say i buy far less Cyborg merchandise because of the issue and would spend more money on DC Cyborg merchandise if they remedied this problem.
The face plate isn't iconic for a fair portion of the Cyborg fanbase at the very least. My personal experience leads me to believe that the face plate is not only *not* iconic for the majority of fans (50.1% or greater) but it's also a detriment or impediment to greater character popularity.
It's an easy fix for DC that doesn't alienate either side.
