Yes tenacity is a community fork that happened during the hubbub with the musescore takeover and telemetry additions and doesn’t have any of it.
It also has a couple of quality-of-life additions and a few new features but nothing specifically different as of yet. Mostly, it’s a good community-lead fork that has some momentum behind it - since it also unifies the developers behind 2-3 protest forks that happened at the same time and I think that’s generally (if not a safe bet) a good thing to support.
