Side point, I was under the impression that Chrome was going to stop videos from auto playing but videos on Reuters still play by default. Any ideas why? Thanks.
They introduced that in one update and then removed it in the next, shelving it until October I believe.
Chrome has never truly blocked autoplay. In some cases it will be blocked, in others it'll just be muted. If you want true autoplay blocking use Firefox.
Chrome comes with a whitelist; it's possible that Reuters is in it.
