Are redirects that expensive? How about giving the domain to another entity that is willing to pick up the hosting and/or redirection costs?
It would be awesome if an other individual or organization is willing to sponsor the hosting costs so we could keep it open longer, if so please email me at sytse@gitlab.com or comment here.
GitLab bought Gitorious so they could shut it down, not so they could give it to someone else. That is the purpose of acquisitions within the same field.
That's a pretty disingenuous thing to say when it seems like the only reason an "upgrade path" is needed in the first place is because of the acquisition and shutdown.
Edit: Even with Gitorious being "no longer sustainable" in its current form, there are other methods that could have been used (price adjustments, fundraising, etc) rather than an outright and very short-term shutdown.
