It's not that good news goes unreported. It's drowned out by overwhelming bad news and the hegemonic narrative.
For example, people receiving healthcare under other states is completely opposed to the hegemonic narrative. Capitalism doesn't give a turd about people in Pakistan, Vietnam, etc. Empire views their progress as a threat.
And, while it's cool that an eye disease was cured, the same system is literally murdering humanity and destroying the planet.
