Here is a documentation link of chromiums conceptual application layer: https://www.chromium.org/developers/design-documents/displaying-a-web-page-in-chrome/ which clearly shows the core of chromium (especially rendering, and API infrastructure by w3) is done via WebKit through a Webkit Port and a glue layer for type compatability.

I never said WebKit and Chromium are the same engine, mainly because chromium is not an engine at all. WebKit is a browser engine and is the core of chromium, chromium is a browser core, but not an engine.

Where do you get the information from that most fingerprinting is done in JS ? Because, in the end, the data has to be sent to a server to be processed (even if the fingerprint is aggregated in a cookie). Which in turn would just be another way of saying its on the backend.

If i do a JS request to the backend bc i want to see album X and its cover, i request the resource from the server. There is no way around this. If the actions I took are saved on a local cookie or the server directly logs the request makes 0 difference in the end as to process the logged action it would've to be sent to the server anyways; else there is no point in logging.

Here is mozillas docs for fingerprinting: https://developer.mozilla.org/en-US/docs/Glossary/Fingerprinting As can be seen the tab itself only has access to the APIs of the hardware down under, which can in turn not really be trusted as any linux user can easily spoof these. Sure you can be identified, as in your browser. But nothing about your hardware. I just did that test and all the hardware info is miles off.

I am not sure what point you are trying to make.
