For the most part, I believe herb Kohl funds his campaigns out of his own pocket (one of the perks of having a net worth of more than $200 million). Claiming that he's shaking down Google just doesn't fly. Unlike like our governor, Senator Kohl is an upstanding guy.
I for one, don't really miss the 'good old days' of downloading 28 or so floppies of SLS over a 14k modem, only to find that disk 7 has a error when you're attempting an install. Or working days on writing and tweaking an xconfig file. I admit, the excitement of running this 'cool new OS' is gone, but it is infinitely more usable so now I can actually get my work done.
