For example, pretty much any question about C string handling has many possible answers, e.g., [1] admits that comparing two strings is "rather broad" and the various answers there recommend looping over each index and comparing chars with ==, sscanf, strncmp, regexes, and PEGs. Opinions galore!

But if you want to know the difference between AWS EC2 and EB [2], even though there's one pretty clear answer, somehow the admins unanimously find the question to be "primarily opinion-based".

My hunch is that due to the desire for longevity of content, there's a large unspoken bias in favor of questions about simple programs, and against questions about remote services (which are more likely to disappear or change, even though that's not likely to happen with major AWS services), and that the question closure explanations like "primarily opinion-based" are just a smokescreen.
