I wish the decent guys who started companies would leave a directive for the company that must be followed to prevent it from becoming just another shitty piece of garbage like everything else these days has become thanks to the geniuses with business degrees running the world.
But there’s no practical way you could hold the future owners of the business to that directive. If you own the business, you get to set the directives, including overwriting previous ones.
The only way to enforce it is to maintain controlling interest in the business. Or, at least spread the interest among multiple parties so no one person can dictate it.
