Replit used legal threats to kill my open-source project

A healthy, competitive reponse to a single former intern one-upping you would be something among the lines of "ok, kid see if you can replicate THIS".

Also a healthy response would be to issue a C&D - assuming they have a case here.

But this? We don't have all the details and Replit might well be in the right here, but still - that's not how you handle such cases.

And I should know, because I've been in trouble regarding my comments on HN with a company I used to work for, but the communication on their side was firm, polite and professional.

While studying fine art I built a site that was intended to experiment with disrupting advertising by picking on a bullshit pseudo-scientific term, "bifidus digestivum", used by the company Danone as the live ingredient in their yoghurts, and ranking highly for that term on Google - it eventually got to the number 1 spot. Danone's legal team got in touch and we danced around each other for a bit. It was clear that the original domain used their trademark and that would be enforceable in court, so I gave that to them a couple of weeks after setting up a new domain that wasn't just their trademark and redirecting all the traffic until Google caught up with the move: https://whatisbifidusregularis.org/ (They'd changed the magic ingredient's name by that point, partially because of the ridicule the initial name provoked). I replied to their emails addressing their points - no, I was not making any money from it so there's no commercial harm, I was just laying out the facts so there was no defamation etc. and after two or three bits of back-and-forth they went away. The site's had something like 500,000 visits since I built it in the late 2000s, which isn't a lot in the large scheme of things, but I hope it helped people who wondered whether it was bullshit know that it was bullshit.

I'm speaking from a UK perspective, so perhaps in the US it's different. While ignoring lawyers is stupid, waiting until they actually get in touch and looking at the merits of their case is not stupid, as the parent comment says. Then if they seem minded to pursue it anyway then fine, back down. But companies don't want to spend loads of money suing someone with no money either. The people who really lose are the people who entirely ignore the lawyers or are determined to take a case to court when they don't have the money for it out of some misplaced sense of righteousness.

All of what I write here is my opinion based on what I have seen referenced in the original post. There could be facts or circumstances that I am unaware of that render such opinion ill-informed. Please don't sue me or take offense -- I offer only insight from quite a bit of life experience.

From the email exchange posted [1], I would say Amjad was right in asking that the repository be taken down. Regardless of intent, Radon's actions had given the appearance of unethical behavior. Bear in mind that, when considering ethics, intent is not as important as appearance. While Amjad's statements were not necessarily optimal, I would not fault him for what he said. There are so many other adversities in life -- we should not make ourselves adversaries of one another.

A couple red flags that stood out:

(1) There is an implication that Amjad's time is owed to Radon. Radon's meticulous documentation and other content posted on the Internet is suggestive of overachievement and perfectionism, traits that can be very valuable in many technical domains. Unfortunately, personal correspondence usually is not one of those domains. One should always be most respectful of other people's time. Time is a non-renewable resource of unknown quantity.

(2) Some of Radon's statements and expressions, whether they do or do not contain truth, are quite adversarial and should be avoided in correspondence. Those that stood out to me are "You are categorically in the wrong," "... you have no legal or ethical basis ...," "... I have acted in good faith ... [and] your conduct ... has been grossly rude and unprofessional," "Despite repeated inquiry on my part, you have refused to point to any specific feature ...," "... your characterization of the morality of my actions is baseless and in bad faith," and "It's a shame that you decided to terminate our relationship this way." In all things, regardless of the circumstances, the first rule should be "Be respectful."

While I can imagine myself in Radon's shoes and empathize with what he did and why, experience has taught me that certain norms of civility, whether they be shallow or even illogical, are expected in discourse. My advise to Radon would be to let the whole thing slide. Life will bring so many more unexpected twists and turns; save time energy for life's truly important battles that are yet to come.

You are right. Other than the brand name recognition and the existing business relationships, I can't think of anything that would be tough for a funded competitor to replicate.
