According to the issues trackers, various forms of "self-hosting would be more work for a lesser product".
I'm not sure that would still be the case if the decision were being made today, and would quietly hope not, but I guess we can charitably say that the reason now is "inertia".
Personally, I think they may have underestimated (or failed to fully predict) the anti-google, pro-privacy sentiment in the wings, and it's clear even from this thread and the issues on bugzilla that it's probably cost them enough privacy-capital at this stage to have justified the extra work required to self-host.
But hindsight is 20-20. There are sunk costs now which also must play into the decisions.
Definitely not, but I can see how it might be useful to know aggregates of the Firefox version and locale information for people visiting that particular page.

Or maybe the "anti-google, pro-privacy sentiment" isn't really all that big. Could be a relatively small but vocal set of people.

The same argument applies to the whole of Firefox. It's more work and it's a lesser product. If Firefox can be a better product, than Mozilla Analytics could be too.
At this point it's clear that Mozilla is a business (with well paid management and staff) like Google that is using Privacy as a promo like Google used Don't Be Evil.
Mozilla might be better in practice today, but it's not on a principled foundation. It looks like a Google Lite - Firefox vs Chrome, Rust vs Go, etc.
We use this one, paid version. Sometimes it's a slower load, the UI is less good than GA, other little issues but we still get the core data, and can trap page-level-events.
