xda is older than github and has a lot of institutional inertia. Also I get the impression that many of the people involved in the xda ecosystem are hobbyists that just kind of learn things as they go along and have less exposure to bigco software engineering practices.

You talk as if github is a daunting service only meant for enterprise customers.

When in reality it's easy to sign up and used by almost every kind of project you can think of, including someone's 100 line random bash script with a single sentence README, a tiny embedded device hobby project all the way to a vibe coded project, from people who know nothing about software engineering. Issues are PRs are regularly used for all those projects. You almost need to go extra mile to not put your stuff on github.

I don't think there is any reasonable excuse/explanation other than "inertia".
