I understand the article writers frustration. He liked a thing about a product he uses and they changed the product. He is feeling angry and he is expressing that anger and others are sharing in that.
And I'm part of another group of people. I would notice the files being searched without too much interest. Since I pay a monthly rate, I don't care about optimizing tokens. I only care about the quality of the final output.
I think the larger issue is that programmers are feeling like we are losing control. At first we're like, I'll let it auto-complete but no more. Then it was, I'll let it scaffold a project but not more. Each step we are ceding ground. It is strange to watch someone finally break on "They removed the names of the files the agent was operating on". Of all of the lost points of control this one seems so trivial. But every camels back has a breaking point and we can't judge the straw that does it.
