This seems like a bad knee-jerk reaction, not a real solution.

My company also has a business portal. Can I take down domains that are similar to it as well? Or is this power just reserved for MegaCorp Inc. who can afford large legal teams? At what point does a company become large enough to warrant "protection" of domains similar to their own? Who makes that decision and is there any dispute process? Etc, etc...

So many questions and potential pitfalls surrounding this approach. I don't know if there's any better realistic "solution" than to let users ultimately be responsible for the domains they visit. Not much of a solution but I don't see any better options that are both realistic and helpful.

There's an ICANN process that allows you to file exactly this sort of domain-specific takedown notice. https://www.icann.org/resources/pages/help/dndr/udrp-en

The big drawback of the process it that it doesn't work well for phishing attacks, where taking down one domain is of limited value. It's designed more for things like nissan.com
