Neither Wikipedia nor GP said something about intentions. My understanding of GGP's complaint is that they'd refer to the package containing the security issue as "backdoor", rather than the malware itself, and I disagree. This driver thing is a backdoor, the package is backdoored, this fits usual definitions.
Perhaps we use the term back door in computer security because it comes from the general English expression to get someone or something in by the back door, which more generally is any exploit?
