People complained IC2 was old and needed to change.
People are now complaining they don't [want? Like? I feel there is a missing word here] IC2 to change.
:/
Some people complained IC2 was old and needed to change. Quite a lot of others were perfectly content with the way things were, and didn't feel the need to bring up the issue. I mean, if you made a thread saying "I like how things are right now, let's keep that", you'd either be reported for spamming the forums, or it'd be an invitation for moaners to drop in and argue against you - those agreeing with you are more likely to like your post than writing several-paragraph responses. As a general rule, the happy crowd is a silent crowd.
Then IC2 changed. Those who previously moaned got their satisfaction. However, the previously happy crowd saw their "product" being radically changed in a direction they didn't ask for. Those were the people who liked IC2 the way it was, those who hadn't played it for long enough to grow bored, and those who knew and loved the way the mod worked.
What's worse, it can be argued that by changing, IC2 keeps the "regular customers" coming back, after all they've got a solid extension and refreshment of what the mod added. On the other hand, the creators just made IC2 a lot harder to get into, especially compared to other mods, and I think it will hurt them in the long run. They had a solid, useful, easy-to-use mod that was the perfect entry-level introduction to modded Minecraft (at least it was for me). It was intuitive enough that other mods could easily be made compatible with it, or expand on what it had to offer. It was broad enough that you could base your base on it, and its addons made it offer help in almost every aspect of the game.
The way it is today, I wouldn't even have considered starting with it if I were new to the game, I'd probably ditch it promptly in favour of TE or something. Now the "old crowd" who asked for revitalization might be happy, but we'll see the backlash from those who preferred things the way they were.
...Either way, it's dangerous to use the term "people" to describe folks complaining on the Internet. It might look like the community is speaking with an unison voice, but upon closer inspection, it's very rare that the same people bash contradictory things.
