They read lot of 'buzzword' on the internet or heard them from their tech friend and ask for everything..

Anecdotally, in my 20+ years of working for website and web app companies, I have never had a client who has even suggested a specific way of implementing an app. The closest has been when a client has asked for a tech proposal and had it sanity checked by a third party. These days I mostly work on "rescuing" apps that a client has had built by one company, found it hasn't gone well, and has come to the company I work for to make it work properly. All of the crazy tech stack implementations I've seen have come from developers who think they're clever, and never the client demanding something trendy.
