There have been discrete points where I would buy a Reese's peanut butter cup and go "Yuck!". We're currently in such a phase right now where I won't buy them anymore.
I really notice when they tamper with the peanut butter. But there have been a couple of times where they over-sugared the chocolate.
Normally, I would have blown it off as "getting old" except that I mentioned that I wouldn't buy one anymore and two children (14 and 10) agreed that they started sucking that year.
I think it's also interesting to note that Nutella (also from Ferrero) has a history of being a post-WW2 pure chocolate substitute at a time when hazelnuts were much cheaper and easier to source. It seems to be in the company's DNA to produce chocolate-based confections while touting chocolate as the bad guy.
The milk is probably the most nutritionally rich thing in your average chocolate bar.
Or have you sampled American chocolates that do not try to follow Hershey's flavor and found that they are all inferior?

[edit] and of course 12oz has replaced 16oz as the “standard” size.
One of the things I like about grocery shopping is practicing mental math, and I calculate price per quantity mentally when choosing between different brands/sizes. It's good mental exercise, and the ability to do that sort of division mentally occasionally is helpful in other contexts.
In most of Europe (probably all the EU countries at least, unified regulations yay) shops need to put the price per 1kg/100g/1L/100mL on the tags, depending on which is most appropriate for the product.

I've told a related story from the same time period on here before about how they stopped putting handles on the large 4L ice cream buckets so they could save 1¢ per bucket. That was the same summer.
