I read that article. To me it comes across as someone spouting off because a company they don't own has the temerity to go off in a direction they don't approve of.
Well, if the author wants to take his ball and go home he can be my guest. When the time is right and it makes financial sense for me to do so (it's been a difficult year here, too) I will be purchasing an AmigaONE. The dongle won't interfere with running other OS's unless those other OS's want it to. It is simply there to protect the interests of the IP owners, and against that I cannot and will not argue.
