The article is wrong in general simply because there is no specific number that is important. It is a gradual change.

no, that's wrong. 50% is a magic number. with less than that, a malicious miner and only undo a few blocks at a time when they run lucky, but the rest of the network will overtake them if they don't publish their side-mined chain asap. but with 50%+1 they can mine in secret knowing they will be guaranteed to have the longest chain if they mine long enough. so with 49% of the network, they can undo maybe 5 or 10 blocks at a time, and they have to publish them right away or risk the network overtaking them. with 51% then can undo 10000 blocks whenever they want without worry. it is a BIG difference and it most certainly IS a magic number.

A solo miner with > 50%? Yes.

A mining pool with > 50%? No.

Imagine for a moment if GHash.io doesn't show any solved blocks on the publicly shared blockchain for the next 10000 blocks (70 days). None of the miners get any payouts. How many miners do you think will continue to run their equipment in a pool that pays them absolutely nothing for 70 days?
