You're right. I don't mean to minimize the effort required. The effort required is a big part of the argument in favor of moving, or at least aspiring to move to a platform with more open and interoperable values. I can't imagine MS will make that transition any easier as time goes on despite forgejo and others best efforts. I've no problem with an OSS projects using GH but I'd hope they'd take the risk more seriously in a discussion about it.

Edit: I also don't think the effort is wasted or insurmountable. Regarding broken links, I've stumbled across many projects that have changed their GH repo to a mirror and link to their new platform. And RE logistical v philosophical reasons, I consider avoiding vender lock-in to be risk management and part of a project's long-term logistics.
