Not sure about that, doesn't sound true.

It is certainly simpler to make a lot of money in the short term by focusing on one core business only. But diversification and redundancy are known survival techniques. Think IBM and Microsoft: both companies do a lot even if they have some sort of a core. But even the core is somehow intermingled with much of the else they do.

It's also not so simple to connect different dots if you only have one kind of dots. Google can combine stuff in novel ways because they're kind of a technological crossover. Not so easy if you've purged out all that clutter that doesn't fit in your core work.
