I preferred GitHub's UI because it was cleaner and much faster to load.
GitLab's initial screen is that list.
It may well be that Microsoft doesn't radically alter the direction of GitHub and that will be acceptable to most people.
(I would prefer a fully FLOSS solution, but GitHub has huge benefits in terms of network effects.)
What kinds of these? Its never been the case that 25% more engineers means 25% more progress and github is a mature product made by a company that already employees a signifiant staff.
The logical thing would be not to piss off the existing users and use github to add value to existing Microsoft properties. So some new integration with Microsoft things?
Also required users making private forks of paid-for organization private repos to pay again to give access to all team members at once last time I used it, but I guess that’s not relevant for open-source migration.
You can also mark it as «Need work».
Better rapport with developers? Probably not.
(and, FWIW, we use Bitbucket/Jira and honestly I'm fine with them - their updates just tend to be full of the annoying things a bad PHB would love and light on the things developers care about)
