Honestly Jules, personal irritation aside, are you “really”[1] that surprised?
wikipedia is pretty much known for arbitrary editorial decisions made by self-important teenagers with too much time on their hands[2].
The stupidity of the whole deal is pretty much epitomized by KvR’s[2] own Babya Logic page[3].
If you put the page back you’ll just end up in a pointless war of attrition with some idiot who actually does care more about the existence of a JUCE page than you do.
