The blobs at the top left are the most visible ones, but
there actually are dust blobs across the entire frame.
And apparently the photographer wasan't even aware of
the dust, as the blobs are on all or almost all images.

Yup!
The dust is very conspicuous, and is going to need some major fixing in
post. That sensor is in dire need of cleaning, and the photographer
should
have taken an emergency cleaning kit with him on that trip. When you know
that you are going to be in an environment with wind, dust, and sand,
there
is no excuse for not being prepared. At a minimum a lot of care should be
taken with lens changes.

That assumes he knows how to use that kit (I don't).

it's never too late to learn. read the instructions

No such instructions on mine. They say to bring the camera to the
service shop.

what cleaning kit did you buy that did not include instructions??

a cleaning kit is *not* going to say take it to the shop. there would
be no point in the kit.

you're really stretching on this one.

They run the service gratis if you go to certain sponsored events, but
they do them some three hours drive from here, and they warn that they
will do only a limited number, so no warranty of getting it done.

My idea is to go there once and see how they do it.

this isn't about going to a shop to have it done and they have
different tools than you would anyway.

or do a search on
how. there are plenty of detailed explanations and even videos. it's
not difficult. even just one squeeze of a rocket blower would make a
dramatic improvement.

Maybe he takes the
camera to a shop to be cleaned by a professional back home that knows
how to do it, and he wouldn't dare try to do it himself, even less on a
trip.

or maybe he doesn't care.

You do not know that.

it's quite clear he doesn't care, else he wouldn't have posted a photo
full of dust spots which looks like utter ****.

he simply does not care.
