Larsson's purchase works because there is a public market, a filing requirement, and an audience that reprices on disclosure. A private company has none of these.

That applies to how you signal to employees, customers and partners — and it argues against gestures engineered to look good at minimum cost, because sophisticated observers discount exactly those.
