The most notable example of something that is "weird" and "a stupid idea" is NumPy... and *everything* in the Scientific Python ecosystem thereby. -- Keeping medicines from the bloodstreams of the sick; food from the bellies of the hungry; books from the hands of the uneducated; technology from the underdeveloped; and putting advocates of freedom in prisons. Intellectual property is to the 21st century what the slave trade was to the 16th.
