I am in agreement however I suspect many developers have never seen the usage of "git bisect" to track down a bug and fix it. Once you see the power of that, I think one can come to appreciate more the granular git history that is present when not using squash commits.

Of course, git bisect still works with squash commits it just makes your job as the bug fixer much harder because typically squashed commits are quite large so you have to figure out what in the N lines of code introduced the defect.
