Do you really stand by to what you just wrote? the implications of this is that one either belongs to the world of corporate software manufacturing (software = black box, guarded by lawyers) or one has no rights and everyone else is entitled to steal their work. Do you steal apples from stalls when you go to the market?

That’s a dishonest response. You’re completely ignoring the fact that your license terms allow this data to be used in the way it is being used. To use your own flawed analogy, OpenDDR is not stealing apples from your stall — they’re eating the apples you freely gave away.

On the other hand, you’re in the position of trying to take back something you released to the community in the past, because you feel people are abusing the rights you gave them. You say it isn’t nice for others to use the product of your own work to build competing services. I say it isn’t nice to tell people they’re allowed to use your work and then turn around and sue them when they do.
