If you don't think what Hellwig did obstructed the project, then I guess we fundamentally disagree. Again, the R4L folks could work around this by getting the code pulled in by Linus, but that doesn't stop the fact that a senior maintainer has made it explicit that they will do everything in their power to stop this.
Code that wasn't his to reject was NACKed, causing a large amount of uncertainty about how to proceed with drivers that use DMA, and around the R4L project in general. At the absolute least, this is plain intent to sabotage (but IMO it is clearly more than intent at this stage). The core of what you are saying is that this has/will have absolutely no impact on anything to do with future R4L progress. The explosion of discussions around this exact topic across various forums with abundant disagreement from maintainers and R4L folks running counter to that idea are irrelevant I guess.
I'm not even a "rust person" and nobody has said anything about "being on the right side of history" except you. If that's how you see this discussion then we're not going to get anywhere. I wish you well, and urge you to in future engage in good faith and consider that not everybody is some boogeyman "on the true path" evangelist.
