It depends on the venture capitalists themselves. Our start-up has little to no interference from our VCs. It feels very much the same as before we got funding, now we just get to keep working. But again, that only says something about our particular VCs.
If they allow you to keep working, I don't see how you can claim that "venture capital kills great ideas."
Sure, they'll want to cash in on their investment in a few years, so the exit might be different from what we would do if we were on our own. But we would have already had to go get real jobs if not for them, so in that sense they've enabled us to work on good ideas.
