But the sense of ownership in #OpenSource can become stale over time as the project ages – and can transform to toxic entitlement and give rise to systemic disrespect against new contributors or against those outside of a perceived in-group.

On the positive side, the sense of ownership of an #OpenSource project can translate into motivation, excitement, a sense of belonging in the developer/user communities, and ultimately inspire community members to contributing productively, acting respectfully, and taking on responsibilities.

What has been happening in the #SageMath project over the second half of the 21 years of its existence can serve as a cautionary tale for other long-running #OpenSource projects.
Much of it can be understood by reflecting on the notion of "ownership" of an #OpenSource project.

#otd 1 year ago I created the @passagemath.org fork of #SageMath, the general-purpose #OpenSource #Mathematics system in #Python.
I created the fork in response to the Sage project's final decline into systemic toxicity; in hindsight, the step was long overdue.

The passagemath project maintains an updated version of the #SageMath distribution, in part for use with #cibuildwheel.
The passagemath-10.6.30 release notes now give an overview of the non-Python packages upgraded in (or only available in) passagemath's version of the Sage distribution.

found an IRL linear program, took some pictures

4 photos showing the same thing from different angles. a convex polyhedron made of glass, with black edges, is held in two hands. the hands wear white gloves, the polyhedron is wider than it is tall or deep. width is around 4 hands, other dimensions are about one and a half. inside the polyhedron is a orange ping pong ball, and is has found its resting spot at the bottom vertex. hence it solves the LP of minimizing height subject to being inside the polyhedron

If there's interest, I can tell the story of #FPSAC, the Algebraic #Combinatorics conference, held at @ucdavis.bsky.social in 2023, where I was invited to (and ... temporarily ... served on) the Organizing Committee in an attempt to mock me for my accessibility advocacy in our department.

Warning: It's not a path to popularity. But advances in accessibility have never been reached by asking nicely.

A long-term approach: Become an ally of the local members of the community who cannot participate in seminars, workshops, conferences, social events in person because of health or other restrictions. Once events are made remote-accessible for locals, they can also be open for remote participants.

Inexplicably, the meson-based build switched to a new, incompatible "sage" script implemented in github.com/sagemath/sag..., which does not implement "-t" (and other options).
