I don't think the idea of advertising with the association of fiber is
only about latency.
Think "symmetrical link" which isn't common even for Enterprise satcom.
IT is true. That symmetrical aspect - upload speed similar to download
bandwidth, compared to a higher ratio ul/dl - is a great benefit in
fiber and ADSL for home users. Maybe the latency ratio could also be
considered.
Also the SLA. Wonder if we can test this link somehow. How performant
is it vs the Ku Band service? Anyone has a connection to the customer?
I suppose it is not yet possible to compare the SLA of starlink
Community gateways, since the starlink Community gateways seem not to be
deployed already. But I dont really know.

PS:
I am not sure what you mean by the SLA aspect (service-level
agreement). Maybe you mean a form of higher reliability and stability
of the user link.
Ku band (12GHz-18GHz) is what typical starlink uses to end users.
Starlink Community gateways might also use Ku band, I think. However,
the photos show these spheres of 'teleports' which probably use
something higher than Ku. I dont know what freqs these teleports use;
and dont know either whether the Community gateways will use that Ku, or
use the D-band (120-170GHz) recently reserved by 'ESSAFI II for starlink
at ITU.
Then there is this Starlink Direct which promisses data (maybe higher
bandwidths?) to unmodified smartphone users in year 2025, which might
also be used for communities, albeit much smaller ('tethering' WiFi
technology). That is at 2.6 or 3.6 GHz (unmodified smartphones).
JIOSpace fiber seems to be at MEO altitudes and also for unmodified
smartphones,, hence around 2.6 or 3.6GHz.
Do you think the 'SLA' of smartphones is high?
