Seems silly, since it's the most appropriate thing for lots of posts that don't fit into the other categories, like "Just got promoted", "I won $500 at the casino today", "My son just got first place at pinewood derby", "Just finished the last chapter for Winds of Winter it's going to the editors now", etc.
That stuck out to me, because those auto-video ads were one of the major reasons I uninstalled the facebook app entirely. Quickly checking some things on my phone while walking down the hall at work, or while some code runs I don't want to accidentally play some loud nonsense, and that happened often enough for me to downgrade my mobile facebook experience back to the browser. I still use facebook, but not the app.
That sort of jives with this anecdote as well:
"When the company redesigned the News Feed in 2013, it looked great on the iMacs in Facebook’s headquarters but made the product harder to use everywhere else."
Most computers aren't macs, let alone iMacs. How could you possibly miss out on testing for even one other thing? It's weirdly close-minded given what facebook is and how it presents itself.
I'm sure the iMac is just a stand-in for "high-end computer with a large display". That newsfeed was gorgeous and would have probably worked well on >90% of US PCs. The problems were with 10+ years old computers connected at modem speed in, let's say, eastern European government offices.
In my experience, facebook has settings reset bugs that can turn off previous settings, sometimes to your surprise. Like a friend group you choose to post to as a default gets reset to all friends without you noticing, or these kind of video autoplay settings.
