He says the checksums are different but he doesn’t provide a diff to show how different. It could just be a single flipped bit or something. And that could happen in his own RAM/disk/CPU/router so seems premature to immediately blame Apple.

There's a corrupted photo at the top of the article and the non corrupt version at the bottom, is that not enough?

No, it isn’t. The OP isn’t questioning whether the file changed, but asking what changed to the file, not what changed visibly.

The visible effect shown could be due to a change as small as a single bit flip. It also could be that large parts of the file got overwritten, or that it partially got zeroed. The exact kind of damage can help pinpoint the cause of the problem.
