Okay where does it say you can't rename the software?
Where does it say you can't say you wrote it?
All that says is you must :
you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty
keep intact all the notices that refer to this General Public License and to the absence of any warranty
give any other recipients of the Program a copy of this General Public License along with the Program
It is just as I thought ... you have no idea what you talking about.
