Good faith will not be sufficient for UMN contributions to be accepted in the future, if maintainers just decide that it's not worth their time. I can think of at least two people sending bad enough patches that they were almost invariably not even reviewed.
I'm sure they can figure out how to submit the changes from Gmail addresses. After all, that's how they submitted the patches for their much maligned study.
What I see are certain Linux kernel maintainers acting in bad faith, spreading misinformation and slandering students.
I definitely don't think it's a good idea for students to be contributing to a project where they get slandered and have collective punishments imposed upon them for something they didn't do. Another reason to recommend that people do not contribute to the Linux kernel project.
Dealing with "I tricked you into taking a bad patch" is not a tolerable patch review environment. And when such contributions use an entire CS department for cover, then maintainers are forced to question all such contributions.
How did they use it for cover? They appear to have submitted them from Gmail addresses. Should contributions from Gmail addresses be banned?
Their study wasn't ethical but it did demonstrate something concerning. It wasn't useless.
Seems like all this fuss is being made because of the embarrassment it caused for the Linux kernel project rather than actual harm.
Now that it's so widely publicized that this is so easy to do what happens when malicious people do this instead of tests for a questionable study?
If I banned entire groups / organizations from my open source projects for having key people who had seriously wronged me, everyone in this thread and most of the people pressing like and retweet would be banned from participation.
