Most regular contributors found this behavior frustrating, and would discuss it privately, although rarely if ever discuss it on-list. These are people who are absolutely committed to free software, they were just sick of dealing with RMS. Wingo's stated attitude seems pretty typical: RMS was damage that needed to be routed around.
After developing this reputation, it's not shocking that most maintainers and contributors accepted his resignation from the FSF with a shrug. They were sick of dealing with him anyway - they're not going to protest to try to get him back.
The FSF owns the copyright to most GNU projects, and RMS has resigned from the FSF. It's unclear why he would continue to have any formal authority beyond his personal power of persuasion.
For newcomers to the projects this can lead to unpleasant interactions that push people away from volunteering on the projects.
At the same time, this shouldn't push you away from getting involved with a GNU project if you find it interesting. Many of the projects are full of kind, helpful, hardworking people. The maintainers in particular are mostly excellent. If you have an unpleasant interaction, I'd encourage you to reach out to one of the maintainers in a private message to ask for advice on how to contribute and work with the community. Often they can help by pointing you to specific people to talk to and interact with.
