Do you have any idea how soul crushing it is to work your ass of on site performance, to have people passive-aggressively question the team's abilities when the numbers are even 100ms too high...
And then when you're done some nosey assholes go and add over 2 seconds to your page loads just so they can do something ethically questionable. And the fact they waited til the end to add it on just proves that they knew it was going to be bad news but they did it anyway.
It sucks. It kills trust for the organization, and it kills respect for everyone in the decision chain.
My coworkers and I joke from time to time about running an ethical advertising network with reasonable software. Well, they're joking. I don't think they know I'm not entirely.
