Interactive rebase is fine, I used it probably 50x a day for many years. The problem isn't really with Git here, it's more a bunch of interrelated problems with GitHub's UX, and the fact that many people culturally have never approached the problem in any other way. A lot of places basically just outright copy GitHub's UX, which I think is a good example of this.
For example, using 'git absorb' or autosquash doesn't solve the problem of the review UX just doing badly when you say "What is the difference between the last version of commit Y, and the new version." If those changes include a rebase, it shows you the entire diff including the rebase. That's often not good, but sometimes extremely necessary. (See my other posts in the thread about how Gerrit does this better.) And if you have to do something like rebase, then solve a conflict as a result of the rebase, it is basically unavoidable that you have to do all of them at once if you want the CI to stay clean (which I find important, at least.)
Also, a lot of teams just culturally hate shit like autosquash, or any squash/rebasing at all. Do I think they're misinformed? Yes. Do I think they could use tools that make those flows 1000x better and faster? Yes. But at the end of the day default user interface and design philosophy of one of the most popular software forges in the world does actually matter and have downstream cultural impact. So you have to interrogate that and break it down for people. GitHub does not really encourage, explain, or smooth out workflows like this. People learn it, then hate anything else. (I mean, fucking hell, Git rebase didn't even have --update-refs, a huge QOL improvement for stacked diffs, until like 2022!) So, you often don't have a choice. I've had many places where engineers despised GH force pushes, but only because... GitHub's UX is bad at tracking addressed/reviewed comments on a PR after a force push! They get hung by their own noose, so to speak, and don't even know it.
I do have other problems with Git, but this post is mostly about GitHub/Gitlab style PR review flows. The same problems still happen even with autosquash or tools that accomplish the same thing.
