I always thought Captain Picard restrained himself very well. He could have done much worse to them. This seemed like a proverbial slap on the wrist - he couldn't just let them go after the crimes they committed, but he did so in a fair but firm manner. It was a good first contact: you can't push us around, but we will forgive you.
I can't imagine what Captain Janeway would have done lol
