If you read the thread, it's not copying, as in building another company with the same premise (like Chipotle and QDoba, or Uber vs Lyft). It's copying, as in replicating the same pitch materials, marketing copy, app flows, terms & conditions, job descriptions, etc.
Honestly, If Bromberg's being 100% about this, it's bizarre. Most engineers I know have so many ideas of their own that aping someone else's whole company without any creative interpretation would feel really miserable. What's their endgame, hire the Eco team and have them continue to generate original ideas?
