# Dechrome
|
||||
|
||||
Dechrome is a tool written in Rust for batch removing Chromium-based browsers and installing Firefox as a replacement.
|
||||
|
||||
> [!WARNING]
|
||||
> The script is experimental and wasn't thoroughly tested on all Windows systems.
|
||||
|
||||
> [!NOTE]
|
||||
> Executing as administrator is preferred in order to remove system-wide installations. Make sure to terminate msedge.exe processes through task manager beforing launching, as the script might fail to delete certain files locked by Edge
|
||||
|
||||
# Reasoning
|
||||
|
||||
Chromium-based browsers hold around 74.05% market share across all devices, 78.58% on desktop, 90.45%* on Windows, according to [GlobalStats statcounter](https://gs.statcounter.com/browser-market-share/desktop/worldwide/#monthly-202307-202307-bar) as of July 2023.
|
||||
> *Calculated by excluding Safari market share from browser market share on desktop, may be inaccurate
|
||||
|
||||
This causes multiple issues:
|
||||
1. Increased attack surface
|
||||
2. Illusion of choice
|
||||
3. Single entity control
|
||||
|
||||
### Increased attack surface
|
||||
Having a single product spread across millions of machines imposes a severe risk in case of discovered vulnerability as the area of attack could be worldwide and the patches could take a long time to propagate, giving opportunity for attackers to take advantage of the situation.
|
||||
|
||||
### Illusion of choice
|
||||
Users are given illusion of choice, no matter what they pick they are likely to end up using Google's product, either [Blink](https://www.chromium.org/blink) or Chromium, since most browsers are based on them and are not advertised as such.
|
||||
|
||||
### Single entity control
|
||||
While Chromium project is open-source, ultimately Google is in full control of the changes being made to it. Giving away control of the web client to Google, entity controlling most of the web space, gives it the ability to shift and control market to it's will, both client-side and server-side. This provokes monopoly and hurts competition in the long run. See recent [Web Environment Integrity proposal](https://github.com/RupertBenWiser/Web-Environment-Integrity/blob/main/explainer.md).
