Facebook is still the big kid on the block and able to set positive trends in social media. It seems strange that the company is bothering to make this seemingly negative change: video sound will be “on” by default instead of muted until the user chooses to listen.
Facebook reported last year that 80% of mobile users react negatively to automatic sound on videos (I know I do). Why the change? Could be that Facebook wants to appeal to people who love Snapchat, and “sound on” is a feature on that app. You can read more about this change here.
Tip: Users can disable the feature by switching off “Videos in News Feed Start with Sound” in Facebook settings.
