For starters, even the article refutes your claim:
"There is no need for such a large, complex structure just to tell if it’s light or dark. What’s more,
his videos of Erythropsidinium reveal that it can point its
ocelloid in different directions"
"....unique and sophisticated eye, called the ocelloid..."
(from wiki)The
ocelloid.... is in fact one of the most complex known subcellular structures
Ocelloids contain subcomponents analogous to eye structures including the
lens,
cornea,
iris, and
retina.
[2] It can be divided into two substructures, the translucent, roundish
hyalosome and the heavily
pigmented melanosome, also known as the retinal body or pigment cup.
[5] The hyalosome serves as the refractive
lens of the ocelloid; it is surrounded by a layer of
mitochondria serving as the cornea and has constrictive rings analogous to the
iris. The retinal body has internal structure reminiscent of
thylakoid membranes in
chloroplasts and contains proteins related to
bacteriorhodopsin, a light-sensitive protein found in some
archaea.
[2][5]
Using
single-cell genomics and
electron microscopy techniques, the ocelloid has been shown to consist of multiple
membrane-bound organelles with distinct
endosymbiotic origins deriving from multiple lineages of
peridinin-containing
plastids.

yes, how simple!- and this doesn't even begin to get into how this collected information is connected,sent, processed and utilized to an advantageous physical response- without which it is utterly useless
So again it's a
fully functional and highly sophisticated eye, fully integrated into the organism. Even if not as sophisticated as ours. And all the literal digital DNA code required to implement this extremely complex system, all spontaneously blundered into existence by lucky random mistake?, hundreds of millions of years ago. Can we observe, measure, test or reproduce in any way.. ?
Of course not, rather it is concluded that it
must have happened, purely because that's what the 19th century theory demands, not the 21st century evidence
