I doubt that the FSF has any problem with cryptography being used to protect 
users from software from untrusted sources so I doubt that they do not 
consider signing acceptable.

The problem with Tivo, as far as I understand, is not them signing their 
binaries and checking that signature before execution.
The problem is that Tivo does not provide an adequate mechanism to register 
new keys. Which of course denies the user at least one of the four core 
principles of Free Software.

I doubt that Tivo asked the FSF whether withholding one of the Four Freedoms 
would be OK and the FSF said yes. I doubt they would even need to ask their 
legal counsels.
