Use whatever you or your company want to use. As long as it is in
compliance with GPL2 (as that is the licence R currently uses) then you
are fine. As to whether what you intend to do is in compliance with the
GPL2, then you'll find only lay-person comments on this list (as far as
I know there are know lawyers lurking on the list that have raised their
heads...), some informed because they have gone through similar
procedures in their work place/business and others less well informed.

If this is really important to you/your business, then consult a lawyer.

R Core are not lawyers and as such you won't see them contributing to
threads like this, other than to answer the basics (e.g. the "what
licence is R released under" type question).

I doubt anyone contributing to this thread would call themselves an
expect in this field, and they are not fighting, just offering opinions
- but I wouldn't base my business model on these opinions on GPL,
licensing etc. You need a lawyer for that, preferably one that is
familiar with the computing industry and software licences. This list is
not the place to solicit such advice, as you have found out.
