Well you don't have to use their browser to consume content on the internet and I never have used it to consume content from their sites.

Now if they start to force it where you have to use their browser to access their content it may be an issue depending on how much competition is in that space.

Or worse, they use their influence on standards committees to effectively lock out other browsers. That would be worth taking them to town over.

Google is no more the internet than any other company. You never have to use google or their products for anything but many do because its just there and it just works
