I was baffled by this as well, until I got closer to it and got to see "how the sausage is made".
It is amazing what a confident, strong personality can do in a group of people in _any_ setting.
We say this because sausage is tasty, but most people prefer not to see all the animal parts being ground up and stuffed into an intestine.
"Laws are like sausages, it is better not to see them being made."
Yes, companies seem such opaque entities from the outside, but they are mostly driven by the wills of the topmost two layers. Remove key players from those layers and you see billions of dollars moving in strange new directions.
That's what SVP/ director level / C-level people do for a living. They don't barely do any coding or any technical work - they create the vision and hire the people (or buy other companies) to make it real.
Of course, reforming one arm of a business is a lot easier than an entire company, especially if nobody really depends on that arm.

Likewise, sure, a big company has a lot of momentum but it shouldn't take more than a year to realign it.
In a big organization, if the CEO says to do something (i.e. new vision... PKI's!), most people can ignore it with little chance of reprisal. It's much more of a political/social hierarchy than a military one.
Think of it more like a feudal society. At the best of times, the headman at the top has the loyalty of most of the upper levels, and each of those has the loyalty of most of whoever is beneath them. But each of them has their own desires and plans: what they think will make the organization better or make their position in it better. At worse times, you have the War of the Roses or Game of Thrones sort of stuff.
The problem with bringing in outside organizations, like buying Boston Dynamics, is that they have their own, mostly fixed feudal structures, and integrating them is difficult. (Consider, at the very least, someone is going to go from the king of their own personal world to having to ask before they head to the executive washroom.)
A single person with a vision can have a great effect, because they only have to inspire (or convince) a small group of people around them to go along and that small group will bring along their own people. On the other hand, if the person with vision leaves the organization, whatever they were holding together falls apart pretty quickly.
(My favorite example is the Westinghouse(!)-CBS-Viacom thing.)
google paid X for BD
google showed off their latest robots
someone offered 2X for BD.
or alternatively:
maintaining and discontinuing BD's government contracts both put google in a tight place.
