Yeah Boogle is a browser that has own blockchain. Its just imitating Google design but totally different from it. Ive try using it and its fast also. Maybe because their browser is new. Also theres a chance to earn BOO tokens which currently traded already and has been listed on CMC. I think this isnt a bad project at all considering the info of their team and everything about it. I do hope they launch a bounty campaign here in forum.
What the op is asking is why is Google not suing Boogle for such similarities in name. It is like a rhyme and I also find it deceitful. I know there is a copyright law against such act. If the project was not out to deceive people may be it should have picked a different name. The only difference is in there first letters, G and B.
