The board is there to protect the interest of shareholders. Having two wildly different 'factions' on the board does not do that.
You seem to be trying to make two different points at the same time.
Comcast, in their latest numbers, makes over half (55%) of their revenue from internet and cable TV (not including linear channels but selling the actual packages). Disney does not compete in this sector. Without that money, Disney does about 1/3 more revenue than Comcast.
I'm sure you know Save Disney was pushed (and possibly secretly funded) by Roberts because Comcast's unsolicited bid to buy Disney was shut down by Eisner. He got in Roy's ear and convinced him that Comcast taking control was the right thing, and thats why the whole 'Save Disney' campaign got started.
