sure. consider code in a web shop that does the shop's own finances. there's no freedom reason for customers to be entitled to get a copy of that code, but if there's AGPL code in there, the user (the web shop) loses its freedom to distribute (or not) that code. same goes for, say, a PDF generator that the shop uses to format documents it must provide to customers. if that's AGPL, the web shop's freedom is again violated.

contrast with the web shop's server doing customer's own computing, say managing shopping lists. the user that the computing pertains to is the customer, and so the imperative is for the customer to have the four freedoms, and this web service should thus be provided in a way that respects the customer's freedom. for the web shop, not being the user of that service, the freedoms are not an imperative: it's not entitled to control someone else's computing, even if it performs it itself
