TPP banning requirements to transfer or access to source code of software
These are rules for States.  It has no bearing whatsoever on the GPL.This prevents a country from forcing somebody like Microsoft or Apple to give up their source code for "inspection" in order to access their market.  It also helps to prevent States from demanding and acquiring encryption or other private keys (there's a separate section that also explicitly forbids mandating backdoors be added).Not everything in the TPP is bad.
