I don't think they get paid either so I doubt that EA would get them to test the game for them :/ A lot of them have been giving criticism of the pack so it's not like they're being forced to say only positives.
It does come across that the update and the pack were not tested properly, especially as so many people have had problems with the game crashing. And over on an fb group a few people were reporting they were still having issues with the Get Famous acting career!
I don't want to judge too harshly though - personally I still enjoy the pack and I don't know the inner workings of The Sims team. Remember they have higher ups they have to answer to. I trust they're working hard and at least they are fixing what's broken...kind of...
