Well, they gave people what they asked for. People have been pretty adamant about "we hate online trophies". So now, without them, people are free to get their plats without online play.
And on a side note, trophies shouldn't be an issue if you're buying your games to enjoy them. Trophies and achievements aren't the end all, be all of game enjoyment.
This is why I say sometimes developers should stop listening to people. There is always something to complain about and no matter WHAT they do, someone is going to be unhappy regardless.
