To elaborate a bit further and answer some questions posed by others below...
1. The Targus 'clicker' seemed to have a rubberized feel to it (to increase grippiness) but it feels like a extremely thin layer of a coating
The Foscam PTZ enclosure has a matte texture/feel to it but I can't determine if it has a coating or not
2. Smell? well my smell sense is not that great, yes, maybe a very slight 'sweet'
3. Same condition as rubber component breakdown? no. it is not hardened (as in rubber capstan rollers, etc. It is more sticky and a slightly gooey, but nothing comes off or stretches when it is handled.
4. I have a bottle of 'rubber restorer' that I use on tape decks, old phonographs, etc. I'll try that but I see it as a softener and if the gear I have is already 'soft' I didnt see this a very helpful.
Brake fluid. I'll try that. Thanks
 
It is annoying to think that this stuff is 5 yo or less and it has decayed like this. This seems like a situation that should be understood & resolved.

Sustained unusual humidity or temperature ?

I had that same issue with a Grundig G6 portable AM/FM/SW radio. After
a number of years (maybe 7 or 8), the non-slip material on the outside
of the case turned gooey/sticky. Like the OP, I tried all sort of
things (alcohol,etc) without luck. I found a post somewhere where
someone recommended a solvent to fix it and ordered some. It still
wasn't easy to get the goo off, but I did eventually remove it. The
radio still worked great. I wish I could remember the stuff I used.
I will try to find it and add to this thread if I succeed. By the
way, there was no unusual temperature or humidity involved. The radio
was in a desk drawer in an air conditioned house for 99.9 % of the
time.

As promised, I looked into what I used. It was oven cleaner.
Here is a link to the blog where the problem was described
and solved:

We remove cured silicone rubber with overnight
contact with mineral turpentine. The product
swells greatly and can then be rubbed off.
 
Drench a rag in mineral turpentine, wrap it around
the item, then wrap the whole in polythene film to
retard turpentine evaporation.

Oven cleaner will etch into some plastics , so check on the rear first.
Its great for removing tobacco stain and with caution , its etching will
remove sun-browning of white platic cases.
Assuming this rubber coating is for anti-slip reasons, is there any
mobile phone/tablet model with this treatment?

This link was very helpful. I wish they would have noted the oven cleaner product (Easy-Off?). I will try the oven cleaner, goo-gone, and the kitchen goo gone. Oven cleaner has some nasty vapors...
BTW, the devices I have stayed indoors, so no humidity issues (unless the occasional 90% humidity days we experience in the summer to be of concern)
Thanks again

Avez-vous un compteur ESR (comme le compteur Bob's Blue ESR) pour

No, I don't.
But generally if ESR is wrong, the capacitor value too !
Anyway, I think of an electrolytic failure.

I agree. We've been using Bob's ESR meter kit in our shop since the late
90s. Handy tool!

One kink I found out: they want to charge you the state sales tax in the
destination state if you do this. I needed *one* wall-wart a while back,
so I mailed them a check. They duly shipped the wart, along with a
nastygram that I owed them 35 cents, or whatever it was.

I doubt to OP even has a checking account, or that he would spend the $17 to do anything right.
 
They state that you have to pay any taxes on their website.

LOL at "checking account". One old-timer laughing at another.
 
The rest of the world stopped using them almost entirely like two
decades ago. I mean we still have them, we just never need to use them
in the 21st century.

I still use them to pay my property taxes and a few other bills that add a surcharge to process my debit card. I haven't been able to set up automatic payments for my new truck yet, so that is paid by check until that is ready.

Thank you, Your Honor!
 
Energy must also be reserved to repair and build the power-generation
facilities, be it solar panels or wind farms. All these facilities need
factories to produce, and factories themselves need energy.
 
I am wondering how all those big solar-panel farms process dead panels
without polluting their underground water ... :)

Just like plastic 40 years ago? Did they predict global plastic and
micro-plastic pollution? Did they decide that it could be fixed?

You worry far too much.
 
1,000,000 years from now, either the problems will be solved, or they will not. But it will make no difference to any of us. Species come and go with relentless regularity - and humans are only one of many tens of thousands of species. Eventually, humans will go. Full stop.
