A GA owner can choose to invest in ADS-B-IN. If the owner does so, the

Unfortunately that is incorrect. Military aircraft will not be
equipped with ADS-B at all, and I'm not sure what the situation is
with aircraft that lack an electrical system. So while some benefit
may accrue to GA operators who choose to invest in ADS-B IN, it is
unclear if the FAA intends to immediately provide weather and other
services via ADS-B, but rest assured, that ALL aircraft will not be
depicted on ADS-B IN displays.
