Holy shit that TOS, is that even legal?
Probably not*, but I suspect the plan is more to discourage isolated users from litigation than having a sound chance of standing in court.
For all the ill one can think of Derek Smart or Goons, in case of a lawsuit they might be a blessing in disguise because the probably compiled of a lot of the actual important stuff that might otherwise have been lost in the insane signalling shuffle and obfuscation via means of noise that is CIG modus operandi. It's been very effective at partly detering constant scrutiny from the media, if you haven't followed it it's just so overwhelmingly confusing to get any straight info that it is probably not worth the effort of being harassed by a bunch of sockpuppets (Like it just happened on the Frontier board and a couple of other ones before) to report on this unless the die is cast for good.
Anyway CIG is clearly showing its hand now : I'd expect an hot mess of an abortion to be released as a "minimum viable product" with nominal indefinite & broken support in the coming two years.
I really hope, if that is what will happen, that Croberts is making serious bank with this because he will probably be done for in the videogame business and have to deal with a raging fanbase, at best.
As a side note, PayPal has announced that two weeks from now they'll now longer accept chargebacks in relation to crowdfunded projects.

* I mean, just the first paragraph :

BY CLICKING THE “ACCEPT” BUTTON AT THE END OF THESE TERMS OF SERVICE BELOW, OR BY USING THE WWW.ROBERTSSPACEINDUSTRIES.COM WEBSITE AND RELATED WEBPAGES (THE “WEBSITE”) OR RSI SERVICES OR ANY OF THE CONTENT MADE AVAILABLE VIA THE WEBSITE OR THE GAME LAUNCHER. YOU AGREE THAT THESE TERMS OF SERVICE ARE ENFORCEABLE LIKE ANY WRITTEN CONTRACT SIGNED BY YOU.
Unless I'm misunderstanding it, it's saying that you agree to terms just by visiting their site or viewing a hotlinked official image from it, regardless of if you're aware or not a new ToS agreement is being brought forward. IANAL but that doesn't sound like something that could be acceptable in court anywhere, save for a couple of ridiculously backward or specific interpretations featured in outlier cases. I'd also be genuinely delighted to see them try to convince judges that everything was just non binding pledges and donations, including the stuff that CIG itself label "sales".
