I've had a number of nice conversations with attorneys over the years. They range from specific real cases and current news events, to totally hypothetical events. Frequently, you'll hear "it depends on the judge". Different judges have different opinions. One may side with you totally, while another will be annoyed that you even attempt to reference a particular thing. That's the biggest thing a local attorney who knows the judge will give you.
In his case, one judge may like that he had no intention of violating the IP of the other. Another may prefer to hear that the violation was coincidental. And a third may not care and put him on the hook for a stack of damages.
Asking for legal help here and expecting an answer that can be used is totally different. An attorney doesn't have all the facts, doesn't know the jurisdiction, and would open themselves up to legal trouble.
If the advice is valid in the attorney's jurisdiction, but not the OP, he could come back and blame the attorney.
If the attorney is giving advice outside of the area where he is licensed, he can run into trouble.
If there's something significant that changes the case, then he gave bad advice.
And just like the aforementioned car analogy, a mechanic online can't give the answer to "what is that noise". That thump may be a flat tire, the bass is turned up too loud, or any number of things.
