LOL, IBM only owns 10% because Yippy owed Vivisimo money, and since Yippy couldn't pay in cash, they paid in shares. IBM bought Vivisimo (meaning they have a license for Velocity, and don't care about acquiring a license something they already own from Yippy). Vivisimo was paid in shares of Yippy, so now IBM owns shares in Yippy.
With a volume even on a tumultuous day like today of maybe 100K shares, there's no way IBM can unload 2.5 million shares of Yippy. In fact, the 1.25 million notional value of those securities is probably a drop in the bucket for them.
Ergo, IBM doesn't care about Yippy. Capisce?
