Being first is worthless in and off itself. Execution and customer service are what counts. If you are:

a) an entrepreneur; and

b) think that "rip-offs" like this one are in some way unethical...

... you need to get your head out of your ass, ASAP!

Taking other peoples' great ideas and applying them to make your own product even better is not called "ripping somebody off". That process is called "business".
