I think that creation of 'generic' (infrastructure - in my understanding)
services does not contradict 'business-centric' definition because, e.g.,
security service is not about generic or abstract safety but about protecting
business interests (scientific results, in particular) and building business
trust; transport services serve the same purpose - allowing business to
operate. Not all services have to implement business services directly but
those, that do not implement them, exist because of the needs of the business
services, not because they are coooool. All this is about money paid by a
business for its benefits. Please, tell me if I am wrong.

rather than:
"SOA is a business centric software design paradigm"
for two reasons. Firstly there are many wishing to use SOA in other
environments such as scientific and although they will put up with
these categorizations they see them as inaccurate.
Secondly, the are also many developing generic services (e.g.
security, transport, transaction, etc.) that they really see as being
used by the business services but not business services.
Also, by removing "business centric" from that statement I don't see
any cases being eliminated either.
