If they legit sold their stock because they believed they would lose the value of their asset in the timeframe they were planning on owning it because of their company’s policy change, then yes absolutely they should be held accountable.

My argument is that this isn’t insider trading, but rather the movement of money for other, legitimate, purposes. I’m not saying it looks good, but it may just be coincidental bad timing that someone wanted to, for instance, pay for a year of their daughter’s tuition, or buy their son a home as a wedding present.

A clearer example of insider trading is a politician’s husband buying and selling shares of companies prior to public announcements of major government policies, coincidentally the companies directly impacted by those policies which their spouse was involved in enacting.
