Well it depends 

People in general like to cling to biases 

Sometimes it's just a matter of learned behavior 

The government is just an organization made up of people 
With their own biases and agendas

Politicians are notorious for their lying 
But that doesn't mean that Sometimes they don't truly believe their own lies
Or occasionally tell the truth

It's akin to the stereotypical car salesman 
Or defense attorney 
They'll give their own mother a bad deal while boldface lying to her if it improves their career or allows them to accumulate more wealth 

These things aren't specific or isolated to one type of group or profession 
They're universal 

People have more of an issue with government sponsored information because it doesn't always align with their biases 
Plus no one likes a bunch of overpaid crybaby liars telling them how to think

However non government funded organizations participate in the same type of spin and sensationalism as the government funded organizations 

Think of it like competing tiktok users
They'll do and say and be whatever the audience wants because it generates more engagement as well as money

There are some that still believe in the truth
But the important things tend to get a whitewash when they're actually part of a big company
