A strong smooth blur is much much harder than mosaic patterns to decipher. Besides, during upload of an image, tg compresses it, which messes up the pixels and colors of the blurred area one more time. It takes 2 (almost) impossible tasks to find out what was behind the blur in the beginning!
Besides, right now we have absolutely no option for this!! Presence of either of the forms is better than complete absence of a blur pen that we are dealing with.
Like what we can choose the pen type, font type, blur could have his types too
