My biggest beef with the browser's unchecked scope creep is that its role as an application platform is fulfilled in a manner that's completely at odds with the original purpose of a browser as a user agent. They're running untrusted third party code by default, letting sites embed spyware, and constantly adding more anti-features. Treating this as normal is insane from an unindoctrinated viewpoint. Acting like people who question this status quo are being unreasonable is an insult to everyone who cares about privacy or security.
