I have been researching and reading about the widespread use of a yellow glue-type adhesive used in various electronics, mostly to affix various components to a PCB to make soldering easier (or to prevent vibrations during transportation, or during normal use).
 
It seems that this compound has been used for some time now (over 20+ years in certain electronics), however, it is very commonly used in CyberPower UPS systems. 
 
The concern over its use is that over time it turns brown and becomes brittle, conductive, and corrosive. From here it can cause damage to PCB components, or even the PCB itself (leading to electronic device failures, and even fires).
 
Even though its use is widespread, the main focus here is its use in CyberPower UPS systems (especially the most commonly sold units).
 
Here are several links to various sources that discuss this issue in greater detail:

It seems that this has been reported to CyberPower by multiple customers, and CyberPower's response back is a generic "There is nothing to worry about, this is false information, and all of our products and units are completely safe."
 
What do you think about this?

Thank you very much for your time!

I have several Cyberpower UPS working for many years now without a problem so I didn't personally encounter this problem.
