The traditional way has been to organise a panel of bureaucrats and a large diplomatic/informant network spread over multiple countries, where individuals often have multiple decades of experience in their area of the globe. Which still throws up some pretty terrible misjudgements; but that is the baseline for a serious try.

Any group who's state of the art information gathering includes having "a PR department" and reading the news shouldn't be trying to make moral judgements in countries half a world away. They're going to get it wrong, regularly, and start sanctioning people who shouldn't be sanctioned. The news is not reliable enough to make snap commercial decisions.

The only strategy that works in practice at scale is providing a dumb service. These companies are not up to the job of international politics, it is too fraught. If they think they can dip a toe in safely they're just taking on risk for no real gain. At best they can maybe blindly support the US position, which is the more morally questionable side a fair chunk of the time. Ukraine is unusual for me in that a country is being invaded and the US troops aren't explicitly involved.
