At Mozilla, we review individual commits and do not squash them. This is probably true of anyone using one of the forges capable of handling patch stacks. ("Probably" because the shop may or may not review everything!) Once in a great while, I will keep the commits separate for review and squash for landing, but that's because I intentionally left things in a half-complete state for ease of review.

When you're looking back at why something was done in a certain way, the review view is more useful than either the squashed view or the stream-of-work view. A human put effort into making it understandable, so it's no surprise that it's more understandable.

Well then you're calling them a liar, I guess.

But even if they're lying about achieving it, the preference they have for reviewing small commits is a preference that makes sense. It's not some nonsense "us versus them" thing.
