It's just speculation as to how this went down, but having been in this position before it's usually not an easy thing to handle. If there's a dispute about impact a responsible researcher will usually say "I still plan on publishing this information on X date". This gives the company time to both convince the researcher the impact isn't as severe as they think and also to prepare a public response for that date.

An irresponsible researcher will either say "I'm gonna publish because I think it's high impact" and not give a date (and then often publishing with no notice on a Friday afternoon) or won't even provide notice.

It's often impossible to know which type of actor you're dealing with until it's too late. I've even had people claim they won't publish until X date and then publish early. You can't just provide public notice or you'll both piss off the researcher and run the risk of accidentally giving the impression a low impact bug is actually high impact.
