> OK, you go to your boss and tell him that because of the marketing team's scripts the app takes twice as long to load. Your boss on other hand says: "Who cares? This is how we make money".
What company do you work for that makes more money by causing your app to load twice as slow? I think it's reasonable to expect a developer to measure and present the correlation between performance and revenue.

I used to work in e-commerce and in spite of my repeated warnings about performance, no boss cared. Then some SEO consultant said "google wants fast websites". Guess who got blamed ?

I'm not sure if you are trolling. Can you seriously not parse out that sentence? It is the ad revenue that makes the money. The app loading slow is a side effect. No one (that I know of) is making money by deliberately making slow applications, just think for a second that makes no sense. However a lot of applications make money from ads.

I'll bite. Do you really do this? If so, I'm seriously curious about how you could conclude a straight line causation (not just correlation) between an increase in revenue by an increase in performance? Potentially for a large scale site like Twitter, Facebook where performance means less eyeballs, but even then it's just a correlation.
You don’t need sound reasoning that could withstand scientific scrutiny. Management won’t be able to distinguish valid from bogus data. Just p-hack until it fits your conclusion - they’ll eat it up in no time.
Where I work we already have people doing this, so I don't have to. If your project doesn't tie directly to revenue it surely has KPIs which would be affected by performance.
