Now and Then: What happened to 5 promising file managers?

Back in 2012, we carried a feature looking at 5 file managers that received little media coverage but which carried bountiful promise. The five programs are SpaceFM, gentoo, Marlin, Eagle Mode, and Beesoft Commander.

How did these 5 file managers fare over the last 8 years? Did they capture any market share at all, or are they only remembered like fingerprints on an abandoned handrail?
