Dont you think they do get in trouble now with authorities and Gen manufacturers ? Every once in a while, websites are shut down and they do have raids here and there with certain factories.
There can be various reasons why they dont get the details right. SOmetimes, when a new watch comes out - factories will rush a quick version out because, its cheap to made and they know people will buy it. Then, they come out with a v2, v3, etc. Do they do this because they know there still improvements to be made or do they do this because with each new version, they know people will buy it?
