As far as I can tell (and correct me if I'm wrong) while other open-source projects might be able to get away with opt-in telemetry, Muse Group has simultaneously (a) raised the ire of other open-source developers with the bungled response to e.g.
https://news.ycombinator.com/item?id=27740550; (b) had technically correct but really optically horrid legal language about potential uses of the Audacity data, which implied a blanket granting of any metadata to any buyer of the company to use as they see fit, even if GDPR wouldn't let them do that; (c) didn't make it clear from the get-go that telemetry would be opt-in, nor make any sort of foundational commitment that it would only ever be opt-in; and (d) hasn't yet reacted quickly to describe their ownership structure in the interest of transparency.
It's a perfect storm of mistrust and crisis mismanagement. And the sad thing is that there are talented folks like Tantacrul, Head of Design at Muse Group, who could really benefit the community with opt-in telemetry guiding their product decisions, who have now been thrust into a crisis management role by this botched rollout, and are unprepared to give the transparency now required. Did nobody else at the company learn from WhatsApp's debacle on this?
It's especially sad because while few would shed a tear for WhatsApp's missteps, Muse Group's holdings in MuseScore and Audacity are literally the lifeblood of hobbyist and student music creators. Mistrust in that software can easily lead to "you know what, I heard bad things about Muse stuff, I won't pick it up" and that would rob the world of so, so much creativity. Muse Group, rein in your lawyers, swallow your pride, and act like the stewards of the future of music that you are.
