I think he was trying to get at something here though: can you run a business that is free for some people and isn't ad based? To which I think the answer could be nuanced. Maybe a large enough population pays $4/month and can thus subsidize some part of the population that doesn't have that privilege. Note I'm not actually advocating that, just saying I want to give the guy a benefit of the doubt that he was trying to move the conversation somewhere new and creative.

I think a lot of these questions have been like that, but ultimately the senators couldn't figure out how to phrase what they were getting at and both sides floundered to understand what was going on.

edit: as an example was another senator, "mr funny guy", who was trying to ask if facebook tracks how people use other apps or devices, I'm still not sure, even when they aren't logged in or something. I saw 3 possible questions that he was trying to ask and they all would have been good but I don't think either of them understood what he was asking so they went back and forth uselessly. Could have been some hard hitting commentary on the bundling of permissions, or the bundling of fb with a phone, or the ability for fb to track other app usage, or the ability of fb to track users on websites even when not logged in. oh well.
