Oh yes, I recently escaped from a company like this. I'm not afraid to name names: ClickBooth.com, a Sarasota company in the affiliate marketing space.
Myself and other programmers that once worked there all feel so grateful, we all get together on a regular basis and feel so lucky to have gotten out.
Here's a funny anecodote. They were having a hard time finding new developers. About 9 months ago, if you look through my HN posts, I posted to a "Who Is Hiring" thread. I mentioned a few of the cool things about working at Clickbooth and put my work email address in my post.
The next day I was called into my managers office. The HR woman saw my HN post. She was upset. For some reason. Still don't understand why, exactly. But it's not "my place" to post these things, I was told. And I should go delete my post. And my manager, he played the "good cop" routine... "I talked to the CEO and I'm not going to pursue this further." Oh, really? How lucky of me. You won't discipline me for, ya know, going above and beyond and trying to attract good developers to the team. Oh, gee, thank you sir, so much, for your kindness.
I didn't mean to rant for so long, but boy, it feels good.
