It's talking about domain names desired by BIG companies. Companies with functional legal departments.
You have no inherent right to a domain name, even if you purchased it first. Those domain names represent trademarks. The only way you can defend yourself from having your domain seized is by demonstrating legitimate use in commerce.
Are you saying these people formed businesses and purchased domain names for the sole purpose of selling them for big bucks to companies that don't exist yet? That's insane.
