Why would Spectrum cut ground wire?

Background: at the end of August I got AT&T 5G wireless home internet and discontinued all my Spectrum services

My single family home has a simple Spectrum install. There is a neighborhood line running underground along the street and Spectrum ran an underground line to my house. The Spectrum tech included a ground wire that connected to the main ground for my house. The main ground connection is outside on the side of my house and I just noticed the Spectrum ground wire has been cut.

Not being at all experienced with the install, I managed to get a self-described "indoor" Spectrum technician on the phone and was told this is common and not a safety problem of any kind.

Any reason why Spectrum would cut the ground wire they had installed? Thanks for any info!

Strange yes, it effects nothing. Did they also cut the coax?

Even underground coax must be "earthed" at the entry point.

I'm surprised that they would bother disconnecting anything at the house, as they usually do that at the branch connection in the hopes that there may be a connection in the future. Did Spectrum remove a grounding block, junction box, or splitter that would have been grounded?

All I could think is they were worried about a ground loop, but they had it when he was hooked up then?
Dosent add up.

I checked inside the Spectrum install box on the outdoor side of the house. All the cables are normal and the ground wire, which is green, is still connected. The cut is outside the install box between it and the connection points for the house ground.

I looked in the basement anyway, since there's no way whoever did the cut, was in the house. In the basement the two-way splitter is right there with both cables normal.
