If Meta is going to use the legal system to bully tiny startups that tangentially compete with them, they might as well take a bit of a PR hit for doing it.
This thread is 1 part "this isn't the place to litigate this" and 2 parts "i've got a beef with big tech", so it's unlikely to be germane and therefore the all caps are likely to be a bit much.
But it's good advice generally, and that shouldn't be downvoted.
Plus, we as a company are (maybe excessively) open. Of course we're going to get involved in legal proceedings, that's a fact of life. Doesn't mean we won't talk about it.
But the GP's advice is still as good as when it was printed: for the most part, the under-resourced party is courting nothing but trouble by courting public opinion litigation.
Do talk to a lawyer, don't say more than you can help on the Internet. It's good advice.
