The anti-tivo clause bans things like Apple pre-installing GPLv3 software on macs, but allows them to let you use exactly the same software as long as they do not give users access to the binary. AGPLv3 blocks both use cases, GPLv2 blocks neither.

On the spectrum of "things that take away user freedom", withholding the source code is bad. Withholding the source code, the binaries and physical access to the computer is obviously much worse! This latter business model is heavily subsidized by GPLv3.
