Any binary hackers to modify the executable of Chrome directly?
What's the point? It's open source. So some people naturally spend the effort to maintain something like https://github.com/ungoogled-software/ungoogled-chromium
In descending order of significance (i.e. most important objective first):
1. ungoogled-chromium is Google Chromium, sans dependency on Google web services.
2. ungoogled-chromium retains the default Chromium experience as closely as possible.
Unlike other Chromium forks that have their own visions of a web browser, ungoogled-chromium is essentially a drop-in replacement for Chromium.
3. ungoogled-chromium features tweaks to enhance privacy, control, and transparency.
However, almost all of these features must be manually activated or enabled. For more details, see Feature Overview.
