I hace been using noscript for like 15 years now. In my experience, it comes down to recognizing what is a required and superfluous or privacy invading 3rd party. Some websites can take me a while to get working, but I have had very few which I cannot figure out.
This is a cultural thing. My wife has studdied German culture, particularly relating to their relationship with their language, pretty extensively and from what she says they are exceedingly resistant to changes to their general language at all. Hence all of the compound nouns for new devices instead of coming up with a new word. Apparently the cultural adoption of “Das handy” for cellphone was a cultural milestone since they actually used something new instead of trying to cram together “Mobile Wireless Vocal Communication Device” into one word.
