> Two popular shopping companies in India exactly did this, they completely abandoned their websites and went native app only. This combined with large set of permission requested by apps lead to worse experience in terms of privacy for consumers.

I'm surprised nobody has commented on your comment yet. I was in a meeting just this morning where my interlocutor assured me that over 70% of advertising in 10 years will be native apps since everything else is getting blocked or abandoned (and presenting it as an opportunity to do all the stuff you "can't do anymore" on browser).
