@plausible I observed the same on some high-ish profile sites that I managed, where we had both GA and Matomo.
In our set-up Matomo used log analytics, so there was no way to block it from counting a visit.
The difference was not that large, about 30% from what I recall.
I wonder how much of it is people blocking trackers, and how much is different math used on GA side? GA math (what is counted as a "visit", etc) has always been *magic*, and I don't mean it in a good way.
This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
