Lowering the barrier to entry by moving from a technology few use (mercurial) to something popular (git) makes sense. Requiring participation on a proprietary platform owned by Microsoft instead of an open one like Codeberg or GitLab is just lazy. If someone wants to contribute to Firefox, asking them to create an account is a small ask, and I’d argue that if they’re unwilling to do even that, then their participation in the community is likely to be far from useful.
