A new policy from Salesforce that bars customers from using its business software to sell high-capacity firearms underscores the risk that large companies will wield their outsize influence to support social changes that lack broad support from federal lawmakers and voters, gun rights groups say.

The San Francisco-based company appears to be taking a page from the banking industry, where some lenders have restricted services to gun retailers and firearms manufacturers, said Mark Oliva, public affairs director for the National Shooting Sports Foundation, a trade group that represents the firearms industry. It’s an example, he said, of advocacy “running amok.”
