Seems reasonable. I do share this concern:
>Breyer argued that what's really at stake in this case is the ability to register domains that are similar but not identical to booking.com. Thanks to today's ruling, booking.com could "threaten trademark lawsuits against competitors using domains such as bookings.com, eBooking.com, booker.com, or bookit.com," Breyer wrote.
Without even buying similar domains, a company can prevent them from being used via trademark law.
