Your web browsing isn't it at all.
If you are on an Android phone go install NetGuard and take a look at the logs.
There are a few domains that come up for almost every app:
1. graph.facebook.com
2. graph.accountkit.com
3. .crashlytics.com
4. .ampproject.net
5. .segment.io
AMP Project is up there. The majority of the apps on my phone now do their content via WebView + AMP.
In this AMP have found their niche.
