It shouldn't; but if you want to, you are certainly free to.
I believe Alden was alarmed about the collapse in media company values, in the summer of 2010. That's why they walked away from financing Jeff's going private transaction, and I'm guessing that's why they were selling the common stock. It's also possible that since they had/have a large concentration in media, that they were getting margin calls, and/or fund redemptions, that forced them to sell.
As for the CEO, one of those Form 4's states that the "shares sold was a private sale, in order to take a tax loss, for the year.". And the other states that the shares were sold "to pay tax withholding obligations".
I'm surprised someone of your caliber didn't catch either of those. I personally think it was classy of the CEO, to not want to mislead anyone into thinking that he was selling because he didn't have faith in the value of the company's assets.
