I feel you, it is horrendous seeing your work being torn up like that. Having anything public-facing on the internet feels like running a liqueur store in a bad neighbourhood.

I am the co-founder of a SaaS in the higher-ed-tech sector (universities, 300+ of them). Going to make sure we implement support for Fathom (in addition to GA, GTM, Matomo) and reach out to our customers. Hope it helps a bit. Our users would also benefit from stuffing less data to G.
