I’ve seen the same thing. You go to pay for something and suddenly half the internet wants to join the checkout process.

Most of it seems to be third-party scripts bundled in by payment providers, analytics, or “marketing” integrations the site owner probably didn’t even realise they enabled. It just accumulates.

The worrying bit is how normal it’s become. If you didn’t have uMatrix, you’d never even know it was happening.
