Since Trello is part of Atlassian aswell - what are good, reliable and above all lightweight alternatives for managing projects without the “pseudo-agile” rabbit holes of functionality?
My current employer shut off Trello and forced us over to Jira and is threatening to disable Planner, so I'm "not allowed" to rely on Planner enough day-to-day so it's possible it is either better or worse than I remember it being in that department. But this Jira outage has me reevaluating, and they haven't turned off Planner yet.
Realistically, though, you're more likely to be able to convince other project members to use the issue tracker of whatever forge they're comfortable with, for instance Gitlab, Gitea, Pagure or Sourcehut.
I've been pushing for an exit from Jira for a little while now, but this doesn't really add much ammo to that argument for me. It's like pointing at a plane crash and trying to justify the company no longer fly people places.
