I looked at the graph first, and misread the version numbers as sizes in megabytes, because that yielded stuff that wasn’t far off matching the curve linearly. “25.1 MB?” I said. “Huh, I’d have expected a lot more than that, but… maybe it’s just ultra compressed? Somehow? Still seems a bit too small. But maybe this article is actually praising Adobe for keeping it down.”

Then Sumatra being 3.something MB seemed possible, for a well-compressed installer.

Ugh, some of these sizes are absurd. I still remember Zoom basically doubling in a single release, as they put a second entire web browser inside the package.
