Apple/Alphabet/Microsoft/Amazon are innovating?

Mostly they seem to be acquiring smaller companies that have come up with interesting ideas.

Apple, especially, appears to be churning out annual updates on a product line that is not changing at all (I'm not blaming them, they're making more money than god, but still).

And pivoting? I guess Alphabet's "it didn't go viral in the first two years so we're dropping it" strategy could be thought of as pivoting, but not really.
