Fair enough.  Interesting to see.

The interference aspect might come not only from omnispace vs spacex, 
but there are other sats up there using ground cell frequencies.  I 
heard last September about vodafone and bluewalker using also unmodified 
smartphones, i.e. ground cell frequencies.  Further, I also heard about 
recent russian 5G NTN satellite put up there in the orbit.  I would not 
be surprised to hear that China, or other country, also has 5G sats up 
there just to listen, just in case.  Not to mention these direct 
bluetooth ground-to-sat experiments.

Interference might be intentional or unintentional.

It will be advantageous to see how this Direct-to-Cell (or to 
smartphone, or to device) feature can be used in some useful manner, 
such as crime scene resolution where there is no ground 'tower' but some 
sat was there and heard that this or that smartphone was connected or not.
