You could take it up with Cisco, who have been certifying "Network Engineers" for decades. I get your complaint; my father is a fully qualified and slightly/weirdly eminent electronics engineer (and IEEE member), so from a young age I've been made aware of the sanctity of the term in that context. But the term has been used in other contexts for a long time, and most people understand the distinction. It's not a hill worth dying on. Best save your energy for more important battles.
