My memory is hazy now but I recall in the mid-90s Gap (the clothing company) suing Genesis Access Point (an ISP) over gap.com and winning. First come first served is the only fair way to run domain names.
What happens if I register icar.com for product that syncs your car to the cloud. Then Apple decides they want to compete with Elon Musk, with their new Icar. Who will get the domain?
What happens when a large company decides to rebrand it's self and wants the domain?
What happens to Nissan? http://www.nissan.com
Mr. Nissan is lucky that he had an existing business that wasn't car related and he only registered his name...
UDRP cost a few thousand dollars. iPad.com, IIRC, was registered before Apple came up with iPad. Plus, iPad is an entire product line.
One of the reasons I used Apple is because it is easy to point to some examples of them acting in bad faith. Iphone and the music side both had legal niceties surrounding them, from all the parties involved.
If if was a small company or a single person in either of these cases, it would generally be a steam roll. Perhaps ipad.com is a squatter but I would want to make very sure before I give the rights to Apple.

I'll grant that domain squatting is bad and not something we should want to enable, but it's also bad to automatically let the most powerful company win. If your name is Nissan and you own a computer store, you shouldn't have nissan.com taken from you because the car company is bigger. If your name is Mike Rowe and you thought to register mikerowesoft.com for your software projects, you're clever, and should get to keep your domain.
