Why would I disable JavaScript? Several reasons, for me. (NoScript): It renders many attacks moot. JS is complex - a lot of browser attacks rely on it, either directly or as a trigger. It really helps with privacy - for example, PanOptiClick currently says that I leak ~12.3 bits of information. With JS enabled, I'm unique from fonts alone! It helps with battery life - the number of times where I've wondered why I'm losing battery life so rapidly, only to find some webpage is idiotically running JS continuously... It helps with data usage - not (generally) the JS itself, but the resources pulled in by JS. Varies from website to website, but in general definitely helps. Webpages tend to load faster - I have iffy latency on this connection, and cutting 2+ round-trips off of website loading times really helps. Now, as to your comment "it would make more sense to use that time to make the sites usable for visitors with disabilities": the simplest way to make sites usable for visitors with disabilities is to make sure they are usable without JS.
