Imagine if somebody got copyright on a number 32. You could not say any more on a Web page that you use 32 bit OS because you were not allowed to use the number.  You could not even write thirty two, or 0x20... Could not send a card for 32nd birthday. Sounds crazy, right ?

But exactly this is happening. Somebody is trying to claim exclusive ownership of one number and sending take-down letters, law threats to those you have it posted on their web sites or blogs.

This is so wrong. Nobody can restrict usage of a number. Any number. Numbers cannot be copyrighted. Not even primes. Not even a really big numbers. Not even the number, like 41425871524967055159433955941880327 * 320.

Numbers are above politics and corporate lawyers. Above DRM and patents.
Numbers are free speech. Maybe the last real free speech remaining  ...

If the above does not really make any sense, maybe this and this will shed some light ...
