The sense I got from the post was: "It's fine for noobs to cut their teeth on small issues, but as one of the largest tech companies, I'd expect more from your commits. It's obvious you're not even trying".
The point of the email is that the submitter is indeed trying, trying to improve their stats within their organization, at the expense of maintainers’ time, rather than working on the kernel in good faith.
I agree with this. It's reasonable to expect more from well-paid professionals.
