Excellent read.
I don't know who said it first, but it is very relevant in the modern age:
"If the product is free, you are the product."
Here's something fun to do next time you are at an IT conference and speaker is flaunting their big data products and/or services: Ask them about the moral implications. They will usually start to squirm and dodge like an AWB member who took a wrong turn and ended up in the middle of Alexandra.
