The intention is you talk all about resolving DNS of the host, TCP things and HTTP etc.

A more truthful answer would include:

- Your email address is sent to launch darkly to get applicable feature flags.
- A gigabyte of data is logged to DataDog
- Details about the way you moved your mouse are sent to segment.io
- A bunch of telemetry is sent to Sentry.
- Ads are injected from Facebook.
- Metrics are recorded to Hubspot.

Wouldn't the corporate koolaid be the justification of Google Analytics and how my salary depends on it? To ignore the internet hype around tracking and privacy? To become an analytics evangelist and see tracking as a powerful utility unlocking shareholder value?

They want you to drink their corporate kool aid, not the consumer kool aid they distribute widely.

Page renders in browser.

As if! First a metric shit-ton of external JS libraries are pulled, then the needed CSS styles are compiled on-the-fly locally in the client, causing the client to stall all connections, then the page gives an “application error” because your client by default denies local storage and cookies.

"Yes, interviewer, when I press enter, uBlock Origin intercepts the request and gets to work filtering ad and tracking sites like google-analytics.com."

Interviewer: "Do you realize this is a Google interview?"

Well ... I don't know if that is "more truthful"

Yes, that's true for many websites - though in some cases only after the page has been rendered, not before - but it certainly doesn't apply to every domain name or website. Not by a long shot.

I'm in favor of raising awareness among internet users, but I'm against going overboard and painting a bleak picture. That's more likely to lead to resignation than to a change in behavior in my opinion.

- Malicious ad fingerprints your browser and runs a zero day exploit.
- Your AWS, GitHub, and npm credentials are exfiltrated within seconds.
- Within 5 hours you are triaging a widespread supply chain attack that started with you typing in a domain name and pressing enter.

Hardware folks will spend most of the time on the different levels of the networking stack. Front end folks will spend most of their time on DOM stuff.

The full answer is so vast that how a person chooses to answer can reveal a lot about them.
