New CDs precoated with a slippery substance: since

I have not purchased any new CDs for years, but decided to aquire a few (50+) Blue Note RVG titles. (only because the LPs are impossible to find at reasonable prices)
I started to polish them and discovered they are all (except one) slippery already.
CDs used to arrive new with no coating and the surface had very high stiction. Only after coating them with a silicon product would they be "slippery".
Now all the CDs are already slippery.
So, when did this start happening?
(I have not purchased "new" CDs for about 10 years!)
And is this coating good enough, or do you find polishing them to still have some benefits

The silicone product I use is a remnant of a box of 100 packets of an early AudioQuest product. The packets were $0.25 each, so I bought a box of them. The packets were supposed to shine a few CDs. I could shine a hundred with one packet. I still have about 30 packets left. (If I could find some more old stock of them I would grab them!)
Now I use a cloth I keep impregnated with the juice.
I also use Meguiers Scratch X on fine marks.
The Blue Note CDs I aquired are all brand new.
