I think they consider the postulates "out-dated" because they can't consistently meet them as often as they'd like. The postulates were getting in the way of discovering (and profiting from) new deadly viruses. In the methodology section of the paper you linked you can see they used the tried and tested method of assuming the virus was present and the cause of disease before progressing with the "isolation" - if one adhered to koch's postulates that assumption could not be made, and therefore the "isolation" of the virus would fail.

If you declare somethig as pathogen you have to present a solid proof that this thing really generate a pathology. Finding that thing in already sick people does not prove that. Declaring something as pathogen just because you find it in some of sick persons proves absolutely nothing. With same shitty logic you could declare cucumbers a pathogen that cause COVID, because most of sick people eat cucumbers before getting sick.

So, proving that presumed pathogen is one and only cause of some pathology is essential. It is about pure logic, and no any demagogy could free anybody from providing that proof.

Since we still have no such solid proof in over two years, all that covid shit is a 100% hoax.

It does not matter, what that particles are, really. That particles could be easily isolated, it is a routine research procedure, but it was never done with that thing they declare as SARS-CoV-2.
