I have been using pure Vaseline for a long time for thick lubrication of home radio devices. The main reason is that it is the most oxidation-resistant lubricant (I don't know about silicone, maybe it is better, but it is certainly less common and accessible). Only the guaranteed service life when lubricated in open places is more than 10 years. Given that in similar conditions for greases like lithium it is only 1-3 years. In addition, it has no oil smell, does not get dirty. Other disadvantages such as low moisture resistance and temperature range are insignificant for our application. I also use it for lubricating bearings. In this case, its low heat resistance plays a positive role. At rest, the lubricant thickens and does not flow out, while it heats up during operation and becomes, as necessary, liquid.
I also use Vaseline to lubricate worn potentiometer surfaces to eliminate clicking noise.
Another positive point - Vaseline is neytral for almost plastics. Oil based grase can dissolved polistirole based plastic and broken its surface.
