Is it rude?

[stonelazy]

I really find some of the SHOW HN threads interesting, in that case asking for the implementation insight of a particular feature or the architecture of product will be considered rude or is it any unprofessional act ?

Not at all. Anyway some features are "secret sauce" "it looks good but the implementation is a mess", so the poster may politely decline to answer.
