> But, because it may save bandwidth or help pages load more quickly, a tiny minority of our users (0.1%) choose to keep it off. This might make sense if you are reading static content, but we recommend that you keep Javascript on while signing into your Google Account so we can better protect you. They don’t seem to explain why though? Did I miss it? Are they fingerprinting the JavaScript environment of my browser?…
Additionally they imply the only motivation for disabling JavaScript is to increase performance and decrease bandwidth. They conveniently don’t mention the other, arguably more prevalent motivations: to increase privacy and security.
Most people don't disable JS entirely, but use something like uMatrix or noscript. It takes more work, but you can turn off a significant number of things that just don't need to be executed and get around a lot of annoying modals and paywalls (or see a lot of blank pages; that happens a lot too).
