I don't really understand the reasoning in the article. Nobody argues that orange is a meaningless word just because it's not wrong to call an orange a fruit.
Sure, a transpiler is a specialized form of compiler. However that doesn't mean it's not much clearer to describe a transpiler using the more specific name. As such recommending someone replace "compiler" with "transpiler" (when appropriate) does not mean using compiler is wrong. It simply means that, outside of some very niche-interest poetry, using transpiler is better!
