You need to revisit your interwebz sources - Propylene Glycol is used in the chilling systems used in breweries, it is not added to the beer itself. It's like saying that synthetic gear oil is added to your chicken because your chicken went up a conveyor belt.
What goes into beer is monitored by the department that used to be known as the ATF - now the tax and trade bureau. While you might not see a label on the can, they know what goes into the beer. Because it's used as part of the manufacturing process (despite not as an ingredient) it has to be listed.
There are some sodas that have the stuff in - Mountain Dew springs to mind - but that drink has bigger issues.
Feel free to carry on with the multiple edits...
