These are all great advices, but very hard to act on. I got hired by one of the big silicon Valley consultencies with the promise of working in teams and great personal development. Had I been there an entire year, I would have worked completely on my own for 9 months. After voicing my concerns for several months I decided to leave.
I think you acted on the advice as best as you could. I mean, I'm guessing you asked about your work environment (or were told).
If there is a bait and switch, all you can do is voice your concerns and if you aren't heard, leave. Which you did. About the only other thing you can do is share your experience, either publicly or via your network (the latter of which I strongly encourage you to do).
There's definitely an asymmetry of power between employer and employee--everyone has at most 1-2 jobs but employers have many employees.
