The aim is communication. When the aim is very precise communication between knowledgeable parties, a technical language is reasonable. Expecting people to learn that language before they're allowed to have even a basic discussion is a recipe for existing in your own irrelevant bubble. It is human tendency to think that the things that you know should be known by everyone, and the things you don't know are probably not worth knowing. On IPA specifically, it can often be overspecified, particularly with regard to vowel sounds and vowel position in the mouth. It isn't clear when a vowel position is determined by accent or by the word, or whether a vowel becoming a shewa is idiomatic. By relating to similar sounding lexemes (or obvious parts thereof), vernacular pronunciation guides have fewer problems in that regard. IPA is easy to learn a little of, but it's a deep deep well to throw people down when all they want is a glass of water.
