I think that "harder to control" has different meanings in different contexts.
I would submit that today's bikes can accept much finer control inputs, and will respond immediately and predictably. However, that means that clumsy or excessive control input will also yield catastrophic results much more quickly.
The implication is that today's bikes are actually much easier to ride fast when you are paying attention to what you are doing - but will similarly get you in trouble much more quickly. You can prove it to yourself by riding a bike from 4 or 5 years ago, and riding the latest and greatest from today. The differences are, surprisingly, pretty dramatic.
