SpaceX's Starlink internet satellites 'leak' so much radiation that it's hurting radio astronomy, scientists say (www.space.com)

Starlink satellites can disturb observation even of those telescopes protected by radio-quiet zones.

Both "on the earth" and "on the moon" provide about the viewing angle of the sky (a semi-sphere). Unless we're tracking an object with multiple of these spaced around the earth to get 24/7 recordings the moon doesn't seem worse...

Even then, with two of these you could put them opposite eachother just barely into the "dark side" (side facing away from earth) of the moon and get nearly 360 degree coverage. You'd have to not literally be on the boundary/leave an earth sized gap in the coverage, but it would be pretty damn close.

Yeah, that's a good point. Though I suppose that some satellites will push at the edge of that, and the further one gets from the Earth antipode on the Moon, the more one will run into that.

Looks like some go out beyond the Moon, like TESS:

Satellites go beyond the moon, but not starlink satellites (or any future competing large mesh network of satellites), they are in in low orbit to minimize latency. I haven't double checked with math or anything but I don't think they should be high enough to be in sight of much more of the moon than the earth is.
