That's a big reason why private businesses are better than public ones. There's no need to push for unsustainable growth at the behest of busybody investors.
Don't know about secretly (they could probably set up a stealth LLC and file it under "strategic investment"), but they've had a stock buyback program for a while.
The problem is that a lot of "investors" actually aren't investors; they are traders or speculators. They demand immediate growth and are unwilling to allow the company to eat losses in order to invest in long term, ultimately more profitable R&D / projects.

Or...they are unwilling to allow the company to eat losses to pretend to invest in the long term, but are in reality on their way to failure (for example). Let's not act like companies, in general, have this figured out and know what's best. Lots of them fail.
If you want long term growth, you're free to invest that way. But don't impose your preferences on others, or assume their method is wrong. The only way speculators, or anyone, can buy shares is by someone else deciding to sell, uncoerced.
that pressure comes from shareholders who want to make money on their ownership stake, whether the company is traded on public markets or not. it's not carl icahn pushing 5-year exit strategies on startups.
