It will be $40 at release actually.
Also, the above images are what the steam page looks like after you start clicking "read more" links... So I like how your "look at how transparent they are" "proof" isn't even transparent. (at least, that is not how the store page for the game looks in the actual steam client, i dunno, maybe the website is different).
It vary much buries the lede. It does not make clear that you are paying more than double the retail cost of the game for what is essentially a special edition that comes with alpha access. Lots of games come with pre-orders and even special edition pre-orders that come with extra perks, sometimes those perks are access to beta (or alpha occasionally), but they are not marketed as "here is a game for $90, but oh yea, if you do some digging, you can get it for $40 six months from now", they are marketed transparently as "here you can pre-order this game for $40, or if you can't wait the six months, get the super special edition for $90 and get into alpha today!" Notice the purchase box doesn't even say "purchase galactic edition" which is what they are selling and would at least hint that its a special edition that is above retail cost for the game... In fact, no where on the steam page AT ALL does it list the retail price, it has the current price, the beta price if you click to read more of their news feed, and then a month for retail release with no price. Yup, super transparent.
Also, not being forced to buy something doesn't eliminate the right to not like or agree with the price of the item. No one is forced to buy virtually anything... Does that mean no one can ever complain about the price of anything? I may not be forced to buy this game, but I am forced to buy games in general (in as much as I am forced to buy anything else, as it is a major hobby of mine) and a developer starting a trend of charging $90 for a game (and not clearly for a special edition) is a scary thought. I mean, console games went up by $10 in price with the launch of ps3 and 360 because the console makers needed to offset the cost of the consoles themselves, and that entire ordeal led to nearly all the big developers selling all games at $60 to start even on PC, where they didn't have extra costs to offset. This is a young industry that changes fast, and poorly advertised new business models like this one can lead to devastating changes rather abruptly.
Not to mention the bad PR this game is currently getting for showing up on the front page of steam like this:
