If you feel so strongly about it, why don't you update the Wiki and redefine "Window Media Center Extender" to mean whatever you feel like it should mean:
I have no problem with the generic use of the word "extender". I agree that's what all these devices do. But as soon as you add "WMC" in front of it, then it takes on a very specific meaning which is precisely to run a remote session of WMC, inheriting access to copy protected content. All devices in this thread besides Xbox and Echo cannot do that, therefore are not "Window Media Center Extenders". So unless that's what you mean, don't use that term. Just say "extender" or whatever other word you think conveys the correct meaning.
If I sold you a "Windows Media Center Extender" and you received a Raspberry Pi with OpenELEC, you'd want your money back. Likewise, if I sold you a "Tivo" and you received a $30 Raspberry Pi, you'd also want your money back. While the Pi meets your definition of "Windows Media Center Extender", it doesn't meet anyone else's (except Charles). If you Google a few other threads on the subject, you'll find there is pretty much a consensus on the definition I've put forth.
