um, okay, pirating first, if you have already payed your silver coin, have bought the game, and are simply downloading an older version of the game so you can play with your friends... im probably going to catch some flak for this but i dont consider that piracy. if you hadnt paid any money and wanted to play the game with friends and so downloaded a pirated copy THEN thats stupid and illegal... but downloading something thats outdated, potentially inferior and most importantly, something you once had and already paid for, is not piracy in my opinion, despite where you get it from.
now, DRM... Yes, i guess Impulse is DRM, dont get me wrong im as pissed off as the next guy when servers go down, but as far as i understand DRM (and i dont claim to be an expert) DRM is simply some method of making sure you are the actual owner, and that you are not some chump who wants a free lunch (and when Entrenchment is $10 download, its actually less than lunch). i dont think thats too much to ask, i mean, if you make something, write a book, paint a picture, anything, you would want to be compensated and acknowledged for your work right? Stardock/Ironclad/EA everyone is no different... except EA etc are blood sucking leeches but lets not get into that. i mean, i downloaded Command and Conquer Red Alert 3 (legally). after i downloaded it, it wanted me to go on the net to verify i was the guy who bought it.... except that downloading RA3's big 6 GB ass burnt out my net connection (i was overseas and using mobile internet) so i had to wait like a month to get internet back so i could play the damn game. i bought a CD version of Crysis Warhead, and, unlike Crysis Original Recipie, where you just needed the disk to play, Crysis Warhead requires no disk, but needs regular uplinks the the net to check that im the guy who bought it... at the time i bought it, i didnt have the net! so again, for like a month to 5-6 weeks, i couldnt play my game! THAT is stupid DRM my friend. given, most people have internet nowadays, but i didnt, and it caused me SERIOUS aggravation. Compared to that, the Impulse server being offline for one night is nothing to worry about. Just curious, if they had taken the server offline to do maintenance (make sure it doesnt blow up) or to increase effeciency and speed, would you still have complained? if it screws up regularly, then, yes, Stardock needs to get its ass in gear and fix the problem, but if they are doing actual needed repairs/performance boosts, then one night is nothing to cry about.
now, from what i understand your problem to be, the servers were down and your friends couldnt update the game... why werent they updated in the first place? why was your version more recent than theirs? if you have a group of friends you like playing with, and you only play once a blue moon, update to a certain point and sit there, that way you can play without any issues with compatibility. regardless, the servers are down, its unfortunate, but it happens... when your cable tv goes down because some drunk schmuck ran into the telegraph pole, do you blame (sorry, im Australian i dont know who provides cable TV in the US) do you blame Foxtel for having a monopoly on your tv? you sit it out and wait. i mean, like someone up top said, if the there was no impulse, and simply a standard website with all the exe files on it, and the server that supported that website went down, would it be any different to what happened to you with Impulse?
Im sorry, i know this isnt what you want to hear, but sometimes things go wrong, and/or they need to be fixed. I live in Australia, thats like 20-something hours ahead of the US, if they take the servers down at 3 am US time, thats like 11 pm my time... and personally, id still be playing then, so, for people in the US who have jobs/school/lives and arent playing at 3-4 am, its not a problem, but for me, im playing at a still decent hour, and i get shot down because time difference sucks. Stardock etc is in a tough position, cut them some slack.
Now, all things said, i think your idea to get a pirated copy is nothing for other people to be upset about, it solved a problem... i hope you and all your friends have updated since then and no longer need the pirated version, but, for its purpose, it served well. like i said, he already paid his 10 pieces of silver, and since you dont pay for udpates (thanks Stardock/IC), and since we can assume he already, at one point, had the version he was downloading, he wasnt exactly stealing, simply overcoming an unforseen (by him) obstacle. However, just because servers go down does not mean that Stardock needs to give up its right to ensure it get acknowledged and compensated for its work, and Impulse does that, and even then, with updates only. You could steal the mint version of Sins (CD) and play forever without ever spending a cent, so insofar as that, Impulse is not DRM. but if you want the latest upgrades and advancements, then you need to pay, and you need to do in so that you get what you paid for, and Stardock/IC makes sure it gets fairly compensated for its work.
