It’s still pure Internet. It’s just no longer pure “web.”
The internet‘s UI is your OS’s networking library. Although it has changed with the advent of mobile (e.g. can we transparently handle switching between WiFi / cellular?) it has no GUI, touch or otherwise.
What you are trying to say is that companies have had to adapt to the possibility that web applications in a web browser will lose out to native applications using web or Internet protocols behind the scenes.
Here's one out of thousands of scenarios that are possible only on mobile: I am in London, I need some cash money but my bank accounts are in euros. The sequence is this: Face ID, then with a few taps I convert the necessary amount and withdraw pounds from the nearest ATM. With Revolut I saved a lot of time and money on conversion alone (though to be fair many other mobile banks do the same today).
This is not just "pure Internet" it's a different medium that brings a lot of new possibilities.
While I did pay an interchange fee I could do this with my USD account numerous times in the past 20 years.
So is it just that you avoided slightly higher interchange fees?

...seems to indicate you feel the internet has somehow gone somewhere.
Kindly, it seems you're a little confused about what the internet is.
