Why should you model yourself after a CEO of a big company?
They need to do a lot of unhappy and not so fun things other people won't do, or give orders that such things are done. They might not be that self-aware and have the same critical thinking you just had in your sentence, that's why they don't mind doing the dirty stuff.
They usually do whatever the extent of the law allows and even a few gray area things, and some... even unlawful stuff.
It's better to have models for yourself that are meaningful. Our predecessors, people that made peace possible in this world, people that are defending our planet among other causes.
As a founder, you can also have your own takes. Also, there are plenty of good books about management, communication and so on that you can learn from.
Also, when shareholders will throw you under the bus and you need to do the dirty work or get kicked out, remember you are always free to leave. They can find another person to run that company, we're not special or rare. Much less a company's CEO.
Maybe a start would be building your company in a reliable and honest pace. No assholery, pay people fairly and respect them. Don't raise money. Create your own example.
It isn't even that hard, given how terrible and silly the average founder/CEO is. There's barely any example worth following.
