Attributing Second-order Citations
There are two simple ways to deal with this, and you can choose the one you prefer.


Describe in the introduction how you found the two papers and cite them both. Choose the one you prefer and mention that you will be citing this paper only. Which one you prefer is up to you: maybe you choose one because of its better writing style, because it is the first one, or because it is the second one and it refers to the first one, allowing readers to find both. Then cite the single paper.
Describe in the introduction how you found the two papers and cite them both. Cite both papers every time (why not?). For example: "Technologies have values embedded in their design [1, 2]."


There are no rules about what is the best way, but you should always consider the point of view of the reader of your paper: what would you like to see when you read the paper? Personally, I have a slight preference for (2) because  it will allow me to quickly find both papers, even if I decide to read, say, only the results section of your paper.

Finally, you can avoid citing the paper "many times" by re-structuring the text in your article: it should normally not be necessary to cite the same paper more than once in the same section, so you will have to cite them only 3-4 times (introduction, methods, discussion).
