They never change really do they? Since the late 80s they've been doing this - whether it was the hard disk space doubling software, the clones of Norton and PC Tools utilities or whatever else they vacuumed up in their pursuit and destruction of rival software houses.
Back then there were all kinds of rumours about cloning software, destroying the originator's sales in the process, then waiting them out in lengthy copyright trials which they eventually won by default when the competitor went bankrupt.
They developed OS2 for IBM, accidentally creating a better product than Windows (it actually had something only the Amiga could lay claim to at the time, pre-emptive multitasking), but if the rumours are to be believed they deliberately sabotaged the product with bad code.
In the 90s it was Linux, which they assaulted after buying Unix from Novel - then claimed that Linux was just a rip off of their product (acting as if they were somehow responsible for all the development of Sun Microsystems).
So.. here we are again.
