I use a project that are licensed under GNU General Public License version 2 or later
The code owner has abandoned the project and announced they leave it public as FOSS on github. The company with copyright is gone out of business (bankrupt).
My question is now that i have updated a lot of the code to a newer version so it will work for a new version of the cms system is created for. Right now the original project does not work anymore.
Can i just take over the copyright, when the codeowner is "gone". (I guess not)
Otherwise, as i read the license. Can i re-distribute the project without changing the copyright line in the files? I would do it as a paid download business model.
