I’m not sure how that dictates the change in founder behavior. Unless you mean that it self selects for moonshot founders who don't conflate their business and passions - or founders that form businesses for exits, than the business.
Do you think if smaller companies were publicly traded more often that there would be headline grabbing poison pill discussions? Small companies getting tricked into buying up their own shares at a premium to fend off a large shareholder’s takeover bid - and people calling the large shareholder’s failed takeover a trick, theft, controversial at all?
I really just think the culture has changed and all of this has been normalized. Nobody is incorporating in irrelevant states anymore for protections against takeovers, the entire universe of eligible businesses is in Delaware now.
So many things are different in the minds of individual humans involved that none of this would be controversial.
