That this is quid pro quo doesn't in itself imply anything unusual. Your comment could be rephrased as "investment through the use of a company's resources is an exchange of business". Quid pro quo can be used to describe an illegal exchange involving a politician, as it could be considered political bribery, which may be why you thought there was some negative implication in the term, but there is nothing unusual in a business exchanging the use of its own resources for an investment or partnership in another company.
