PHYSIX OBSERVATION

H2O.ai taking over the jdupes fork shows it values the balance between data safety and deduplication speed. For users, this means the tool may receive more sustained maintenance; but the fork also brings compatibility risks, and existing fdupes users should watch for differences in later versions. Deduplication tools are shifting from pure speed to safety first, a signal worth watching.
