You don't only have the option of storing what is essentially a hyperlink to a web page on your Home Screen.

If the web application is structured correctly (according to the specs Apple provides), you can download all the assets for the application and run it locally on the iPhone. It is still a "Web application", but it runs locally and will remain installed even if the web page disappears.
I have created such a web application before. It's not very difficult.

I am certain that it doesn't have access to the same APIs as a native application, though.
So the idea that Apple is promoting this as an alternative to the AppStore is laughable.

Not the ones doing research.

WTF - you know the building was closed and blockaded (poorly) with signs saying the area was closed

Guilt by being guilty - trying to defend these people makes you the "arsehole".

Let's say that your entirely charitable way presenting what he said is true...
1) Trump has no business proposing novel methods of attacking the virus. Especially in stream-of-consciousness ramblings in front of millions of viewers
2) It still demonstrates a fundamental misunderstanding of how viruses work. Once inside the body, viruses are not "on the surface" - they are inside your cells. If you use UV light or disinfectant to kill the virus - you kill the host as well.
3) he is a moron.
