A monopoly has a specific definition. It is possible to illegally influence a market without being a monopoly. Bulldozer was a poor design, and there are no excuses to be made for it. AMD competed just fine - in fact DAMNED WELL - even against earlier shady Intel behavior from 1999 to 2006 or so. But you will recall, that when they had the fastest products in the market, and began approaching that 50% market penetration number, they charged a premium price for them because they could.
Monopoly - the exclusive possession or control of the supply of or trade in a commodity or service.
Emphasis on control and just because at one point spot sales reached 50% does not invalidate how much of the market intel possessed. None of that has to do with the topic at hand. A judgement was made against intel for using illegal practices to artificially control AMD's growth.
Again this isn't about the merits of technology, it's about illegal practices, which you seem to gloss over, marginalize, ignore, etc.
Again, you're making a category error. You know, I see this shit all the times these days. People trying to put a moral and ethical spin onto a corporation. It's like when Nike endorses some dude making a popular political statement and people think "OMG Nike is such a good company because they support [some dude]." No, they don't. They're just trying to sell some shoes to somebody, and gullible customers are buying into this spin. Intel, and to lesser extent, Nvidia have done shady things because they are in dominant positions, and wish to stay there, not because they are more or less moral than the competition. I tell you this, because if AMD continues to excel, at some point they may establish a dominant market position...
...and then you will find the shoe is now on the other foot.
Nice irrelevant example. Almost an appeal to popularity. Making a marketing mistake by coming out with a Jeremy Epstein just do it line is not illegal in any way.
Long and short of it. You could be right, someday AMD will corner the market and screw us all over. At this point it has not happened so arguing as if it already happened is disingenuous.
