History context for the clueless that only goes as deep as the article titles:
Everyone who managed to hold yahoo stock after the dot com bubble (yahoo was the only one that did not tank, so you had to be pretty loaded to survive with stocks after that) also holds lots and lots of microsoft stock.
before google, yahoo was the only competition to microsoft online.
Now, you have tons of stocks of a close-to-monopoly company, microsoft, that pays some dividend. And then you have a few stocks from a runner up that you can't really control and do not pay dividends.
What you do?
1. you call your friends at Goldman&Sachs, ask them to publish an evaluation of value-assets=$0 (reason why first poster made the joke about selling the chairs. Media manipulation was that easy on the 90s)
2. Wait for the market to panic. Buy all you can to get control (i.e. become activist).
3. crash and burn company so Microsoft can buy the remaining market
Now you killed the only competition to microsoft (remember, we are in the 90's here) and microsoft can become a sort-of-monopoly on yet another market! and that is a company you already owns tons of stock.
that is the reason they professionaly-killed Jery Yang, because he suggested a buy back.
Here we are in the next century. And the same is happening. Why? because those companies now, having lost the google ship, called their friends at goldman&sachs and asked for another fake evaluation: facebook. And that is the reason you are seeing all those "barbarian at the gates" histories on Yahoo yet again. And all those evaluations that ignore all the millions on profit and say that yahoo is only worth the BABA stocks.
