I’m an avid cooker and I fucking hate the auto play video on serious eats.
I like to think the people reading that content are not as susceptible to annoying webpages but I think I am wrong.
The relevant metrics would be things like returning visitors, not necessarily time on site or clicks on "mute".
The problem is that there's no way for people to set it to "off" as an option, and that any time this option is suggested or implemented someone will see how they can override it, because "people don't really want to block the videos our our site".
media.autoplay.enabled = false
Most of the worst web UX I’ve ever seen has been through browsing a news site in landscape mode on a mobile. You’re lucky if you can actually read anything at all with the sticky headers, popup banners, modals that don’t fit the screen and break scrolling, and floating videos.
Not representing my company, etcetera, but some agency ours used turned on all the default settings, and rarely goes back to turn off trackers for campaigns they're no longer running. When someone in house was managing he had only turned on what was required, and cleaned up old campaigns.
I also worked with a user Friday who had noticed links via emails were no longer working. Turned out ublock/Firefox was stopping at the iContact tracking URL. She wasn't sure who to report it to, and wasn't using iContact for her emails, so sat on it until she ran into it when we were meeting.
Based on personal experience, marketing groups usually use whatever their IT department approves, and if they're managed, certain browser settings are being pushed to whitelist these based upon users saying things aren't working. Easier to just push a setting than explain best practices.
