I wonder how much they paid to acquire that Instagram @palm account (unless someone who works for them registered it early... Let alone the palm.com domain)
It’s alwyas been a personal account and is my nickname since I was a child.
On a side note, someone has tried to reset my account dozens of times throughout the years.
My guess would be it would depend on what the original use was. If you had a brand in a different sector and offered it I’m sure they could complain but they likely wouldn’t win. (see nissan.com)
