I have always personally seen XL (and amithlon) as a burst artery, bleeding the Amiga to death. But even I am taken aback at this action. Ainc have recognised the threat this emulator poses, and have acted to stem it in a cynical and ruthless - if very effective - way. Or perhaps I'm just reading too deep into this. But that's certainly what it looks like.
The ethics of this are very questionable. In fact, it is a very dirty trick. But such things are common in the business world, and I will leave it to the reader's discretion as to whether it can be justified.
Just think about this: all I know is that this will be good for the sales of remaining amiga hardware and sofware. But perhaps the price of this success is too high. I can only begin to anticipate the anger of XL users.
