I shouldn't have to fight my own product.
And he shouldn't be able to profit off of my work by claiming it as his own.
Both valid points. If he did copy that's a huge D move, but hey your the one who wrote it so you know the inner workings right?
My dads friends with a guy who started a company helping people on healthcare sue the government (or some shit like that) for money they deserved, and eventually it got huge. He then sold the company and created another to combat the company he just sold, and it took off because he knew exactly how the other company went out the lawsuits as he was the one who built it. He then sold that to and owns like 5 mansions.
What I'm saying is if your the one who built it use that to your advantage. You know the flaws and areas it lacks in, create a script that does better in those areas so people are forced into buying your product over his.
