I am of the opposite sentiment. I think it would do wonders. It's very easy in a mega-corp to completely lose track of what the product is, who the customers are. And my intuition is that most VPs at mega-corps think about products in the abstract and focus more on politics & empire building/strategy than actually caring about the customers - and it definitely shows for companies like Google.
Just last week I tried to spawn a GPU instance on GCP, and despite being very familiar with the space (I work on cloud infra), after 20 minutes of fighting the overly complex UI and ridiculously broken flows, I still hadn't my instance up. In the next 3 minutes, I signed up for Lambda Labs, entered a CC, clicked a single button and ssh'ed into my VM.
That's what any start-up focuses on: the product. And that's why they always win over bloated mega-corps focused on internal processes and infighting, whose employees self-select for being complacent about mediocre products as long as the monopoly keeps printing fat paychecks.
