Would you count Heroes 5 in there? Here is what it was in a nutshell - Ubisoft planned to (surprise, surprise) put DRM on it. Or rather StarForce - a particular brand of DRM that had very, very bad name - from being branded a spyware, through actually destroying your machine (the CD drive in particular) to not actually working, it was known to be well...pretty much everything that could be wrong. Gamers went into an uproar and shouted Ubisoft into submission - finally, Ubi decided to use a different DRM scheme. It wasn't a launch thing, but it was resolved just few months before the launch.
At any rate - while keeping the Ubisoft theme, there was the Assassin's Creed (or was it AC2?) release when they introduced the always online DRM. And it backfired spectacularly with the servers going down over the weekend...and I think more than once, too. Also while Ubi were claiming that the always online thing was "uncrackable" it...was, it was crackable very easily and only legit customers suffered from it. Eventually, Ubisoft stripped away the always online requirement, I believe, while just leaving a single check on launch or something like that.
And on a similar note - DRM again but not Ubi, it was EA and Spore. Dear god did that not go down well - there was a limit on the installations you can do which...did not work at all. I think it began with 3 but changing stuff on your PC or just reinstalling the same game on the same machine took one out. If I remember correctly, EA increased the installation limit to 10 (which didn't help) and eventually scrapped it altogether. The damn DRM, again, only hindered legit customers and a large portion of them, too.
There is also From Dust but I don't know much about it, to be honest. I believe it had a horrible DRM scheme which was stripped away eventually due to the sheer amount of complaints, and as a total dick move, brought in again with a later patch.
If you're looking for more general uproar things, then I can suggest Heroes 4 - the game...didn't do well. It was the successor of Heroes 3 (a VERY well liked series up to that point) but it just changed too many things. It wasn't bad, per se, but it was plagued by just being...weird and had some strange decisions put into it - some brilliant, some not so much, some...just strange. A fan backlash followed and even though 3DO (the people that held the series at that point) produced expansions for it, they never actually recovered and went bankrupt to be sold out similar to how THQ ended up. R.I.P. 3DO.
And not much of an uproar but it was a troubled launch - Vampire the Masquerade - Bloodlines. It was going to be a great game, when I first read about it, I immediately set my sights at it - a modern day vampire game, where you choose between a range of distinct clans and you also have a variety of options how to resolve a quest? What could possibly be better? Oh, it was going to use the Source engine. The Source engine. That was just over the top in the amount of coolness - it was the first non-Valve game licensed to use the engine, which note, wasn't even out at that point but looked absolutely amazing with each new tech demo we got (and eventually with Half-Life 2 itself). However, Activision decided to push the release back a bit, just a tiny little while. Or to be precise they decided to have it out on the same day as Half-Life 2. Gee, if that wasn't a stupid enough decision, they also shaved months off the development time, and it turns out Troika Games were given a beta version of the Source engine to work with and that's what they shipped. Also, Troika games were being disbanded as the launch was going on, too. Thanks, Activision! The game launched in a very unfinished state - version 1.0 is pretty much broken. The patch for version 1.1 came out sort of at launch or very close to it - Troika worked on it on a shoestring and a pack of gum budget. Then they did patch 1.2 on even less and...that was it for Troika.
EDIT: Oh, I also remembered about the Demigod launch. Here is a link [http://forums.stardock.com/346815] but it more or less went like this - Demigod (a DotA clone) launches and many people connect to the servers, too many - a sixth of the connections were legit, the rest were not, which brought the servers down.
