The upshot is, while it doesn't make Other M a great Metroid game or even a great game, the original Japanese hits way, way different. Federation Army Samus is much more of a petulant child, and she doesn't crush on Adam so much as view him as a surrogate father. There's a line that in Japanese was something like "I didn't hate Adam for making me feel weak" and in English was like "I was fond of the way Adam would call me something delicate". Implying that while young Samus loved and admired Adam and her fellow soldiers, the way they condescended to her stuck in her craw. Eventually (after the incident with Adam's brother Ian) Samus couldn't take it anymore and struck out on her own as a bounty hunter.
This changes the story of the game significantly, and makes Samus more of a feminist than a lifestyle sub, more fitting with her character in other games. It also makes the story more redemptive: Samus is a prodigal daughter, and she and Adam are struggling to repair their broken relationship. Another line, by Adam, rendered as "I now authorize Varia Suit use" in English, is in Japanese more like "Turn on your Varia Suit right now!!" More desperate, more "What the hell are you doing, you idiot?!" Meaning that Samus didn't leave her Varia Suit off as some sort of token of submission waiting for Adam's command to enable it. Maybe she just forgot to turn it on? She seems more stressed and not functioning at full capacity in this game, as the bit with Ridley shows.
As for this article, I feel like the author is trying to hammer home a point, like "you are the monster, wiping out the helpless metroids" or something, which is just -- no. Metroids are living bioweapons, created as such by the Chozo with various attempts to revive and cultivate them by the Space Pirates and Federation Army. They can't space travel on their own, but they're usually carried to new places by other races intending to use them for their singular purpose. It's not their fault that they're indiscriminate killers, but wiping them out seems like the sensible thing to do (especially at Metroid II's point in the tineline) when they were engineered for destruction, letting them fall into the wrong hands almost inevitably leads to disaster, and you have the occasional incident like the metroid gain-of-function research depicted in Other M, which portends even bigger disaster. I get it -- deconstruction is pretty much table stakes for modern criticism, meaning you haven't truly analyzed a work until you point out how it subverts its own putative message. But that's not really a good thing. The Metroid lore pretty much reinforces at several points along the way that metroids are a galactic threat.
