I don't understand what is the problem. If you made your API public, you want people to use it. If another company decides to use the same API, it is only good, in my opinion. It is very similar to an issue with phone chargers. There were times, where each phone manufacturer had a different charger, and if a new company decided to use a charger desing from Nokia, they would probably sue them. I am so glad those times are over and we use USB everywhere. Arent you glad, that your API could be used everyhwere? Or another example, imagine if every web browser had a different "web language" like Javascript, and developers would have to make several versions of their website for each browser. And if a new browser wanted to display webpages ment for Firefox, Firefox would sue them.
