Rebirth is a different beast, and am sorry to say those guys are getting what is coming to them (to a point).
ED is not released, it isnt even in full alpha and any money we have paid is a pledge/pre-order.
in effect we are entitled to very little and what we do get is a bonus.
but X Rebirth is a released product full of bugs and was not ready for release.
Sometimes I see the ability for on the fly patching as a bad thing. Sure it is great that issues CAN be fixed now, but I think it has made some devs complacent, releasing what they know is broken code with a view to fixing it later, and this is never a good thing, and (aside from elite 1st enc and MSR on the dreamcast which were both very unusual occurrences) these things did not happen 15 years ago.
Say what you like about MS charging for excessive patches, and I am not saying that system is perfect either, but at least - in theory - it encourages at least something like a working product from day 1..
