Perhaps; some eval software (which this *could* be seen as) has stuff
just "turned off", while others have elements ripped out. Ripping out
bits, though, requires more work and regression test - especially for
gratis software, since you don't want to leave the prospective customer
with a bad impression.

It's always hard to know for sure unless you have access to the code,
that's for certain.

If that's the case, then they've done a fair amount to identify the value
of that to them.

Well, no, you "offer" it in exchange for the goods or services. If you
don't offer it, then you don't get the goods or services.
