What could be causing traceroute to only show gateway and final destination?

I am expecting trace route to show pings all along the route like as on my computer (as is often true, there are a few "Request timed out"). THis is meant to demonstrate the problem its not about the destination IP in the example. We both tracerouted to this random IP far away:

But my friend has Google Nest wifi and he gets only reply from his gateway and end destination:

What could be causing my friend's trace route to behave this way?
This suggests that something very strange is going on with Google Nest. Does anyone know why this is happening?
