The great debate on the software blogs about TomTom violating the GPL is
sheer nonsense of the same caliber as Eben Moglen's nonsense about a
copyright license not being a contract.

and only needs to be accepted when redistribution occurs'

'If this argument were valid, no copyright license could permit a licensee
to make multiple copies of a licensed program. That would make not just
the GPL "illegal": Heise's supposed theory would also invalidate the BSD,
Apache, AFL, OSL, MIT/X11, and all other free software licenses'

The GPL, however, is a true copyright license: a unilateral permission, in
which no obligations are reciprocally required by the licensor. Copyright
holders of computer programs are given, by the Copyright Act, exclusive
right to copy, modify and redistribute their programs. The GPL, reduced to
its essence, says:
'You may copy, modify and redistribute this software, whether modified or
unmodified, freely. But if you redistribute it, in modified or unmodified
form, your permission extends only to distribution under the terms of this
license. If you violate the terms of this license, all permission is
withdrawn.'
