Did you create this account, three minutes ago, just to reply to this post, one minute ago? Maybe the accusation about the link between infiltration of OP’s Slack and these HN accounts cautioning legal action and saying to jUsT eXeCuTe BeTtEr has some truth…

Been a lurker for a while and just wanted to comment on the post. I still think recommendation still stands.

I'd rather have the discussion be about the benefits of legal action vs executing instead of how long this account has been around.

That's not always as easy as you seem to want to make it. It can take a long time to establish a field and a product line, a copycat can skip all your mistakes and take the end product. Now: it all depends on what was copied. They've copied code, text from the website, other documentation they may well be in serious trouble. And then it helps that they happen to be funded because that makes them a nice fat & juicy target. The last thing you want is to sue some party that is penniless.
