Usages exist inside contexts, and the context of the post you replied to was unambiguous. Changing it like s/VPNs/services advertised as VPNs/ would not clarify anything to anyone, and changing it like s/VPNs/proxies/ would be less clear (since the author was likely referring to commercial services, not servers in a network).
