I'm not sure your actual beef is. Do you object to all "updates for profit" in principle or is it because Baldur's Gate is somehow "above it"? It's not like they are charging full price. They are taking 12-15 year old games and updating them to properly run on todays hardware for a measly $20 convenience fee. I think I would agree with you if we were talking about games were recently released (i.e. metro), but these are old games.
In spite of what you say, the modded versions of the original games are not equivalent. Content wise they are, but they don't run near as well. With the EE versions you can zoom in and out and pan with ease. The original, modded versions chug on current drivers and widescreen is an afterthought that requires compromise. Until you've experienced the buttery smooth scrolling from the EE versions, I can definitely see why someone would stand by their mods.
Of course no one is forcing you to play the EE versions, but disavowing them due to profiteering is silly. The originals weren't developed pro bono. As long as Black Isle gets a piece of the action then I'm totally on board.
