On this topic, I was reading this blog post from Mozilla
Most people are probably all too aware of how companies like Microsoft leverage their position as the provider of Windows to make it extremely difficult for the end user to switch to a browser besides Edge. Google is also quite bad for this, at least within their native apps.
It’s a bit of a sad read honestly, Mozilla and other browser competitors really aren’t being a fair chance. Though I believe there will be a version of Windows in the EU which alleviates this.
