Have done this twice recently. Did not own shares in either company outside of likely ownership in 401ks or index funds. They don’t check. Ridiculously effective.
I wonder how this could apply to American health insurance companies, where the company is very open about how diametrically opposed the interests of their investors are to the interests of their insured. I can’t even figure out how I would phrase my displeasure as an investor that the dirtbags at Anthem are denying vital healthcare to their “customers.” I suspect they’d reply “You’re welcome!”
