I think you're both correct. Engineers are still susceptible to ads, but are more often than not able to remove them.

Also, you have engineers/developpers like me who actively boycott products when the ad was too intrusive/take me for an idiot (sexualized ads do that for me). I've never bought a Ubisoft game since 2013 or a for the first reason (and avoid Razer), and the second one makes my toiletry shopping interesting.
