I suspect that it's because Firefox makes extensive use of "private" Apple APIs to be able to efficiently render on the platform, and Apple doesn't allow such uses for apps distributed through the app store. Similar issues apply to electron apps: https://news.ycombinator.com/item?id=21437255
If all you're looking to do is avoid Ubiquiti breaking GPL not necessarily binary blobs/100% open I'd recommend just using the Intel AX200. It's 20 bucks, will have longer support, supports AX, and supports more features/extensions on older versions of Wi-Fi than e.g. their AC chip does to boot.
