It's been clear for quite some time that terms like "Extreme", "Pro" and "Max" are marketing terms. They are not accurate classifications of how they will be used. If people feel strongly enough that the name is not accurate, they will have to buy a competing product that fulfills their needs at the price they are willing to pay. I suppose what would be interesting, but highly proprietary, would be Apple's marketing…
It's hard to name the more expensive version to convey it's better without in turn suggesting the cheaper one is shittier.
"Pro" lets you do that by suggesting that it's for a different audience, allowing consumers of the budget model to save face so to speak (I don't need it because I'm not a professional).
