Wherever the term might come from, I am inclined to disagree. Many websites today are so bloated with third party scripts and tracking, that those things far outweigh the actual content. Often the content could be a simple text. Instead the websites create an artificial need for transfering megabytes of data and higher CPU load to give me annoyances. Only through using an ad blocker, I can avoid the bloat. Many people will not avoid it and so the website creator shares some responsibility for the energy spent on loading and processing bloat.
