GitCode, a git-hosting website operated Chongqing Open-Source Co-Creation Technology Co Ltd and with technical support from CSDN and Huawei Cloud.
It is being reported that many users’ repository are being cloned and re-hosted on GitCode without explicit authorization.
There is also a thread on Ycombinator (archived link)
This could be illegal for git repos that do not have a open source license that allows mirroring or copying (BSD, Apache, Mit, GPL, etc.) Sometimes these repos are more “source available” and the source is only allowed to be read, not redistributed or modified. I would say that this is more of a matter for each individual copyright holder, not Microsoft.
But ultimately I agree, this really isn’t as big of a deal as people are making.
edit: changed some wording to be clearer
