What’s their policy when someone buys one of these systems from one of these dickheads?
Most likely their policy is the same as the one Microsoft has for their games and consoles. Microsoft once told me, we’re sorry you purchased a banned console but banned consoles cannot be unblocked, buy a new one next time.
JK Rowling doesn’t believe Transgender people are the sex they identify with and as such is labeled a TERF, Trans Exclusionary Radical Feminist, and many, especially on the internet believe she should be boycotted and no self respecting person would give her or her properties any money. You typically will see some form of that comment in most postings related to her or Harry Potter.
