Hmmm, I hadn't thought of that, since obviously it's not real ownership. I can see an issue of interpreting it as "do you care enough to buy this person", then who buys who would be symbolically important. As I said, I haven't noticed it with those apps, but many facebook things seem to try to tug at your heartstrings like that "if you care about person X, participate, otherwise you don't care". I found that annoying bullshit. Now that I consider it, yeah it is offensive that the same things are probably being said with me as person X.
