For some reason, none of the people here have given you the information you actually need.
Spring is an engine with multiple games and multiple lobbies.
Evolution RTS usually uses weblobby. When you download it, you are accessing the lobby, not the game itself. Once you log into the lobby, the moment you join a multiplayer game, the lobby will download all needed game versions, maps, and engine versions. This make the updating process very fluid and more of a user hands off approach.
Evolution RTS (And practically every other game) uses an update system called "rapid". Rapid takes your latest downloaded game version, and compares it to what has changed in the latest version, and only downloads the parts that have changed. So instead of a 6gb patch blizzard style, you end up with updates that are little more than a few mb.
That said, if you didn't get past the TOS, then that would be the largest issue. I understand the concern about it, and yes it's helpful to notify us of it, but if we really wanted to do something nefarious to you, do you really think all of our sources would be on github and do you really think that we would try to use a TOS to screw you over?
That's what I mean wrt paranoia. A healthy dose of paranoia isn't a bad thing, but it helps to direct it to the areas that make the most sense (like is this game downloading a script that will take nudes of my dog and send them to my cat???), and in a project such as this where the source is very visible and very public, it doesn't really make sense to hone in on a TOS (but thanks for the heads up that it's 15 different types of screwed up in that dialog!).
I don't usually check this forum. I have a google alert set up for "Evolution RTS", which is why I saw this one (I never bothered subbing to the forum). If you need me directly, the steam forums are your best bet, either those or the lobby, but I have been out of town for almost a month so my presence has been pretty sparse.
Usually everyone gets together to play a bunch of games sometime around 5pmGMT on saturdays. Usually people jump on mumble as well. You're welcome to join!
