I'm not really upset about this. I developed an MVP for a product. Not an entirely new idea, but a slightly new twist on the models of the existing competition. About a year later, there was a well-funded competitor doing exactly the same thing. They had millions of VC dollars and a large team compared to my solo effort. They replicated my architecture (which was somewhat novel) and I found remnants of my copy on their landing pages and in their docs. They leapfrogged me with a lot of hard work, but I am a little annoyed by it. I think in reality they just took some inspiration from me for something they would have done anyway.
