Tell me, why are people so bothered by Bitcoin now?
These people hate Bitcoin for the same reasons they hate gold, Ayn Rand, Ron Paul, and libertarians.
They know they are second-handers. They know they are parasitic leeches. They know they are useless tax eaters, living off the productivity of virtuous rational value holders.
They hate anything and anyone that threatens to dispel the illusion that they are moral, and superior to their betters via the sanction of the victim and death worship of altruism.
They know their time is limited, and the day of reckoning draws nigh. They know they will perish when the IRS agents' US dollar paychecks cease and the welfare checks stop.
They hate this reality, and will strain with every misguided
ounce gram of self-preservation to prevent or delay the inevitable.
They are ashamed of their own worthlessness, and have created this entire world order dedicated to hiding their shortcomings behind a tissue of lies and a wall of coercion.
This is awesome.
As for the OP, it's not even vandalism, it's Wikipedia working as intended. The coterie running things over there kept Bitcoin off Wikipedia for a very long time (you might be able to google the record of that drama).
Things like the debate over global warming are purged, and Wikipedia presents one side of an argument as 'consensus'. What Wikipedia's insistence on 'consensus' means is that only one view will ever be presented and the most aggressive group purges all dissent. And the most aggressive group over there is an authoritarian left-wing - that hates sound money. Knowledge is power and their goal is to limit and shape everyone else's. NPOV is of course totally Orwellian, they've simply declared their POV as 'neutral'.
