No, it's to "ANY THIRD-PARTY" (emphasis mine of course).

Notice that this is to *any* third party, not to just customers. This is what
should force said company to give anyone the source on request. You will
notice it doesn't say only to those that purchased from them.

This doesn't apply to the company directly, but rather to its customers
redistributing GPL'd source code.
I am not a lawyer (would be interesting to hear from Wendy on this one) but
as I read it, if you distribute binary only you *MUST* provide source to
anyone who requests it. I did not see any type of stipulation that it must
be to paying customers only. As a matter of fact, using part c) above, if I
get a copy from you (who did pay), I can get a copy of the offer for source
code given to you by the company via part b) and they'd have to honor it.
Short answer: they have to give the source code to anyone who asks. If they
don't they seem to be in violation of the GPL, talk to a lawyer. :)
/me kicks the soapbox away.
