Almost all ideas are copied in some way. Even if an idea is original, not all of it is. Most successful companies aren’t the first one to offer whatever product they’re offering. Everyone is working with what came before them and building on it. Very few things are wholly unique. There is nothing unethical about it in itself.

The problem is when a large company muscles small ones out unfairly (using their clout, money or lawyers to push competition out).
