Contrary to what the simplified/traditional categorisation might suggest, there is nothing non-traditional about the simplification scheme. Most, if not all, of the simplified characters are taken from existing forms, such as those used in cursive script(草书, aka grass script, cao style) and variants used in certain eras/regions which happen to be simpler in forms. There had being painstaking and rigorous process to validate established usage before any character was approved for inclusion, in order to ensure the coherency and continuity of the whole writing system. During the cultural revolution, there was an effort for further simplification, and in the revolutionary zest, the process was not so rigorous and many poorly designed and indeed ugly forms were invented and included. Thankfully, these late additions were later repealed and are no longer in use.

There was (or still is, politically motivated, I think) opposition to the simplification in Taiwan, but fortunately pragmaticism prevails and nowadays, even the current President Ma Ying-jeou advocates "识繁写简" (recognize complex, write simplified), because the practicality of the simplified version is undeniable.
