I used the advertising and employer situations separately. I think you're noticing that I mentioned being fired when talking about advertisement - by "advertisement" I meant by proxy all of the related data storage / exchange / leaking that accompanies it. What if Google gets hacked or sold and the new owner of their data sells a background check service on your searches? Or what if an advertiser tries to target to suspected drug addicts, then turns around and uses that info unethically?
I understand what you're saying about your employer, but there are different levels of self-censorship. My level of self-censorship for friends who work at the same company as me would be very different compared to acquaintances at the company and my boss. I'm ok with the first one because it's what I would do for my friends anyway. I know there are ways to toggle privacy/whatever to affect what people can see but at the end of the day I'm always going to assume my employer can see any regular post I make on Facebook through one means or another.
