I'm not entirely sure I understand your post..... the official kodi development team has nothing to do with Genesis or any other privacy related add-ons. In fact they expressly forbid any mention of it on their forum/wiki etc.
As for the developers creating their own 'private search engine', by doing that they would be directly breaking copyright laws and in all likleyhood be sent to prison for a very long time.
In summary, given you are so ill informed on all things kodi, copyright law and python (that's the programming kodi's add-ons are written in) related, I find it very hard to believe you've 'been with these guys from the start' and really shouldn't be passing comment on what coders should or shouldn't be doing.
