What's your source on that? Would be interested to hear more.

Aside: They seemed to like their Linux containers in 2014[0]. No idea if they're still using the same technique, or have maybe moved onto Kubernetes?

Only anecdotes from several people working there at different divisions. I think I've seen it mentioned here at times as well.

One of the lead devs - years of tenure - on one of the Android backend teams had barely heard of the name and wasn't sure what it was when I brought it up 2 years ago.

Linux containers including Docker are absolutely widespread as I understand it, though.
