Again I'm in favor of choosing browsers on install, but lots of Chrome installs on Windows is not the same as being the default.
So much so that you even get this annoying popup from Edge when you try to download Chrome with Edge - which should be against the rules imo.
A company "accusing" someone of piracy isn't proof. Access to the internet is almost essential these days. If you can prove a person is pirating prosecute them under the law with fines or even incarceration if warranted. But stripping internet access from someone shouldn't be seen as an acceptable punishment for a free citizen anyway.
Whoever owns the network attached to the IP address also shouldn't be responsible for actions of every user. Let's ban an entire company, college, or government institution from the internet because an IP showed up on a list... dumb ruling.
