@mattburgess Yeah, this fighter jet runs on software and jet-fuel only. Everyone knows that a fighter jet does not need any maintenance or replacement parts ever. (it's not like a John Deer tractor where all components can be built/replicated elsewhere) at 100mln$ a piece, you can easily risk bricking it.
@mattburgess Why buy something from a producer who works against you and you need to break the warranty in order to make it do what you need? There is a huge risk of ending up with a badly functioning product or worse a bricked product. There are producers who will work with you and even share their technology.
