The geographically distributed group still has the fun time of excluding one or more of its possible members.
The OP is right. Because DDI must be used in groups, a significant number of groups will always be looking for alternatives to DDI - one that doesn't make them exclude some of their friends. I really think it's a bad business decision.
You make it sound like they have to kick him out of an existing group. Not so much, since the group couldn't exist w/o the VTT (okay, they could do PBEM or something, but we're assuming a group that hasn't found a solution, yet).
A better analogy (and one within my RL experience) would be someone who has kids. They may find themselves without the time to game. Their group isn't kicking them out, their own choices are excluding them. In my case, I still game because the kids can play in the other room, but I miss out on a
lot of movies, concerts, etc. that my non-parent friends go to. They aren't excluding me. They're taking advantage of an opportunity that isn't available to me.
You could also take the example of the guy with a nice-paying job, but long hours. No time for gaming, but he has some other perks (I'm assuming Macs come with perks other than missing out on software). He could find a different job (i.e. change to PC), but that's a choice he has to weigh. If he doesn't make the move, his friends aren't excluding him, he's made a priority call.
The VTT isn't the only way to game. It isn't even the only way to game online. It isn't even the only way to have a virtual table-top online, IIRC. It's just the offerring from WotC in that field. No one is going to come to your house and beat you or hit your IP with as DoS if you use one of the other options or decline to use any option at all.
It's a tool. Something over and above anything ever offered by WotC before. It's existence denies you nothing. It does, however, offer another option to the majority of people. Get over it.
They could have used Java, thus ensuring that it ran poorly on all platforms.
