Websites install to my phone and behave just like native apps (Progressive Web Apps) and native apps don't need installing anymore and behave just like websites. (Instant Apps)
The lines are blurring. I don't know what to believe anymore.

Valid point.
What is happening is that are trying to find more ways of giving a client side application elevated access to the core system resources on which it's running without compromising security part.
Android doesn't want to give some js app many accesses and so, restricts it to the browser vm,🤣
But wait, they come up with progressive app for their own kd chrome...
And then insta app...
End result, it's all same,
Blurred lines...
