>any software project that is driven by a BDFL wouldn't be open source, including Linux.

There are certainly a push in that direction. And that you need a group of people, core or council to be considered as Open Source. And Linux has that.

>The terminology hasn't drifted that much.

It depends how you measure it, but Twitter and HN are at least two places where lots of developers are suggesting Open Sources equals to Community driven. And yes, there are also some movement towards MIT, BSD or Apache 2.0 as being not considered as Open Source because they do not contribute back changes. Although that hasn't gotten any traction.
