Perhaps well-intended, the auto-scrolling content can be a real nightmare for multiple groups of users. I've done a mobile app audit and turning on screen reader exposed quite a messy experience - and yes, web can suffer from the same issue.

Auto-scrolling content creates serious accessibility problems, particularly for Android TalkBack screen reader users who experience constant, annoying audio cues (earcons) that make apps nearly unusable. The issue affects both native mobile apps and web pages on Android, though iOS VoiceOver is unaffected. Beyond screen reader users, auto-scrolling harms people with cognitive disabilities, those who get distracted easily, users who rely on zoom, and those with sensory sensitivities. The recommended solution is to eliminate auto-scrolling entirely or provide manual pause/stop controls, as even WCAG-compliant implementations still create poor user experiences.

Please do not use auto-scrolling content on the web and in applications – Bogdan on Digital Accessibility (A11y)

Scrolling on mobiles, using TalkBack screen reader (Android phones), emits sound cues

Please drop auto-scrolling or at least make it possible to pause or stop
