The article discusses how web bloat affects users with slow devices, highlighting that many modern websites are unusable on low-end devices due to high CPU usage and large page sizes. The author tests various websites on different devices, including a Tecno Spark 8C and an Itel P32, and finds that many sites are slow or crash on these devices. The article also notes that older websites tend to be faster than newer ones, and that sites that use modern techniques like dynamic loading tend to be less usable on low-end devices. The author argues that this is a problem because many users around the world use low-end devices and are excluded from accessing many websites.
