Yes, and if you contribute from an e-mail address that Greg K-H's scripts don't understand, you get an e-mail from him asking you to disclose your employer if you're willing.
Some companies mandate you contribute from your corporate address, and it is impossible to contribute from some corporate e-mail accounts, since they don't allow SMTP access for use with git send-email. For example, my understanding is that this is the reason for the linux.ibm.com subdomain, though someone at IBM can probably elaborate.
LWN's numbers are probably pretty close to accurate, as I think most people disclose. I haven't read TFA, but I guess Oracle is counting only commits to kernel/+fs/+net/ or something like that.
