The only icky thing here is that you're not ok with people leveraging their work experience to potentially get new jobs or network. I used to have my email/LinkedIn in my HN profile and once I even got an interview offer. People also network when they have like-minded interests. If you are competent enough and worked in other places, then the largest probability is that you left the company by your own accord. It doesn't matter if a company is prestigious or not. It's not fun and games. It's work. People leave. But the funny thing is that even Recruiters don't really care about whether you were fired or not. If you worked for one, two, three years? That's a positive sign, even if you're fired. Unless someone only stayed for the probation period, they're good.
