You'd have criticized anything they did with the money. Stock buy backs you'd have claimed they were artificially pumping up their stock price. Bigger dividend, well is 3% yield not enough for you ? If MSFT stock were to tumble, as you often predict for all stocks, that yield would grow and dwarf your savings accounts.
So tell me, what should they have done with the $26 billion ? They decided to try to be a dominant player in social media for business. Might work out, or might be real bad. They can afford it. The number of users involved and cash involved in these new IT areas is massive and hard to understand. I'll be damned if I get my head around the money that GOOG and FB make, but it's real. My only take on this is being #1-#3 globally in any tech area involving the net seems to be really lucrative these days. And anything less then that can quickly put you out of business.
For example, AMZN is massive and is finally monetizing their growing market share. They are literally driving many traditional retail companies right out of business. IBM is in gradual decline because they are losing the war in certain new areas. LinkedIn looked pretty Mickey Mouse to me years ago but it's become the go to place for many professionals.
This deal may upset some MSFT shareholders, maybe even rightly so, they could have benefited from a cash cow monster dividend. But current shareholders have done well and could exit their position today and lose at most 1-2%. LNKD shareholders did real well today. Remember GOOG used to just be some freeware search engine that I used before 99% of people did ( word of mouth in the IT community ) and there was no indication they would become huge.
