The article does eventually mention the current state-of-the-art, but only after perpetuating the misconception for some paragraphs, and that is poor form for a pop-sci article.
No, it is mori, attested in marine, muir, maryadah, mal, morje, etc in farflung IE tongues today.
What's really interesting is that in Hawaiian, a close relative with some sound shifts (k/t, l/r, n/ng, so taboo is kapu in Hawaiian, in Māori, tapu, path is ala / ara, the God of the sea is Kanaloa/Tangaroa) they have more than one word for ocean, kai is coastal waters, moana is the deep ocean.
But it makes sense in the geographical context of both societies and how they evolved to their environment, the Hawaiian archipelago is made up of multiple smaller islands separated by waters exposed to the full force of the Pacific, while the archipelago of New Zealand is dominated by two large landmasses separated by a narrow strait that together are about the same area as Germany.
So the Hawaiians remained more tightly wedded to the sea to build their archipelagan societies than the Māori did.
In fact, the Māori lost the knowledge to build ocean-going vessels like the ones that had carried them to New Zealand within a few hundred years because there was no need for it. And their language lost the distinction between "coastal waters" and "ocean" while Hawaiian retained them.
While we have evidence of Māori traveling to Raoul in the Kermadecs early on, as classical Māori culture evolved on much much larger islands, their technology focus on boats switched from ocean going vessels to coastal travel and river travel.
In fact, while "Wai", water, is often considered the Māori word for "river", there's another word that also means river in Māori:
"Ara" - path.
(Of course, it still means a regular path)
That’s probably why the lake is called “Steinhuder Meer”.
In low German the word for ocean still is “See”.
Die See - the ocean
het meer - der See - the lake
de zee - das Meer - the sea
I don't remember being taught "die See" but I also dropped my German course after one year (which I now regret). Anyway, I always thought this was an interesting development in our languages.

In many of the daughter languages it does regularly include saltwater connected to the world ocean (certainly the Latin "Mare Nostrum" for the Mediterranean!); it just seems uncertain from this description whether it necessarily had that sense in PIE.
That doesn't seem like "had no ... word for ... 'sea'" is a very clear or helpful description of the situation, though.
(I actually remember asking the professor why they had a word for "ocean", but he wasn't sure either.)

But in Livonian (an almost extinct Finnic language spoken in Latvia), Valdamer is one of the names for the Baltic Sea. So maybe that's the origin of the Finnish term as well.
Most likely a reference to Houses of the Holy.
Of course there were other reasons languages changed, and the inheritance is only one factor.
But in some sense there are many lost languages hiding inside contemporary ones.
Did we have Ancient geeks?
I’ve been doing a bit of reading on the Bronze Age Collapse recently. It was such an apocalyptic event that Greeks forgot how to write and read.
Before the collapse, Greeks were using Linear A and Linear B. It took them a few hundred years after the Bronze Age Collapse to learn how to write again, this time borrowing the Phoenician alphabet.
Imagine what an event would look like today that would take us back 200-400 years technologically.
If those technologies were concentrated amongst the elite and only a handful of palace scribes could write most people would have no or little contact with writing. Same with most people living outside of the palaces (overwhelming majority) and who had no access to the amenities.
It’s hard to say what happened but these collapses sometimes have paradoxical outcomes e.g. we have evidence that the quality of life and health improved for Western Europeans at least in some places after the Roman Empire collapsed (less population pressure, no crippling taxes etc.)
“Solon, oh Solon!” — are Greeks truly ancient or relative newcomers in a seafaring land?
