Any advice on how to technically change it but keep the HN submission live?
Someone Created a Startup Just like Mine and Here Is Why That Is Awesome
And changed the link to:
https://blog.nugget.one/upstart/someone-created-a-startup-ju...
It's like getting mad that you like woodworking and publish your projects online and then someone else decides to take up woodworking and publish their projects online.
Your article is both resentful and positive...I'd edit it to be more positive about the validity of what you're doing and not publicly bash this individual for getting excited enough to do the same.
After posting to HN, is it okay to edit the title and change the tone of the piece a bit at this point? How does that "look"? Is there precedent on HN for such edits? I've seen it done effectively elsewhere.
Personally, I like when the dialog continues, I like to see an article writer evolve his position after taking time to listen to, and fully grok the feedback he's getting. But, is that just me?
The word "Stole" implies something was taken, something was lost, something changed possession. Yet, the services are not identical, Nugget offers much more value for its customers, has an established trajectory and customer base. I don't see what has been "taken" from you, here.
Perhaps change it to:
“One of My Customers Created a Look-alike Business, and Here's Why That Is Awesome”
or
“One of My Customers Duplicated My Business, and Here's Why That Is Awesome”
or
“One of My Customers Copied My Business, and Here's Why That Is Awesome”
