That's an interesting thought. I agree with you that most of those products are loss leaders for data mining and thus advertisement.

But my thinking was that if you simply cut off advertising all the products still have massive marketshares and could lean on each other, as long as some succeed. Not to mention investors probably willing to prop up such a massive aggregate marketshare (one only has to look at Uber).

If you 'silo' them, success of one division of previously-Google won't lead to all of them dominating.
