This isn't strictly true though. Google Analytics has a free and a paid tier with GA360, which is for larger businesses.
More to the point, half of these aren't suitable for marketing decisions when you have multiple paid entrypoints to your site. The major, but simple, ones for marketing;
* Channel Groups - being able to merge multiple UTM tags or referrers into a single channel for comparison
* User Retention - even privacy first, it's important that you can track user activity onsite via a logged-in user ID.
* Bot Removal & IP removal - Excluding an office from the GA stats is important to track actual users compared to your colleagues checking in on details.
* Channel comparison for conversion rate - i.e. Google Ads vs FB Ads.
Fathom seems like the top one from this, but it still doesn't have any of these features. It has self removal via the console, but that's not quite the same. The dashboard Pirsch shows doesn't show any of these features, and most of them seem to have filters, but no general comparison windows. Same for Umami.
