Now that you own it what's to stop you from pushing out a new version with a slightly reworked string pad function under a commercial license (say a $100 per use fee)? Could make quite a pretty penny. Kind of crazy that this is possible at all.
Why on earth would someone pay for that if the code is already open source?
Since old code is under a very permissive license, then the new owner could create v0.0.4 add code and make the new version closed with a restrictive license.
This is where a license like GPL would benefit overall, since all future code requires to be under the same license.
Either way, it seems like a dangerous policy to allow someone to re-own a previous owned and published module. Licensing is not the real threat but malicious code that potentially could be deployed.
