*'''Degraded accessibility''': Dynamic and/or active content is well-known to have poor accessibility for users with visual and/or cognitive impairments. While standards such as [[wikipedia:WAI-ARIA|WAI-ARIA]] were created to mitigate this, it's no silver bullet, especially when developers aren't aware of ARIA.

*'''Lack of transparency''': To optimize network bandwidth, JS code is typically served in [[wikipedia:Minification_(programming)|minified]] form, which makes it harder to understand for humans. This is particularly problematic if the original source is not publicly [[wikipedia:Source-available_software|available]], which is typically the case of [[wikipedia:Proprietary_software|proprietary software]].

*'''Excessive tracking''': JS is much more capable than HTML and CSS '''combined''' to track user behavior, because of its first-class access to [https://developer.mozilla.org/en-US/docs/Web/API user-agent (UA) APIs]. JS can communicate with almost any server (only limited by [[wikipedia:Cross-origin_resource_sharing|CORS]]) at any time (limited by connection availability), using a plethora of protocols. JS can get hardware information and compute a [[Device fingerprint|fingerprint of the device]], user, or both.

*[[Personalized Ads|'''Targeted ads''']]: JS makes it harder for [[Ad block|ad-blockers]] to block ads, since it can be used to make overly-dynamic ads. The data collected by malicious JS makes it trivial to serve personalized ads, even across unrelated sites.

*'''Market control''': JS (alongside [[wikipedia:WebAssembly|Wasm]]) are built into almost every web-browser and UA, including "light-weight" ones (such as [[wikipedia:W3m|w3m]]).
