I've written a post regarding the claims about Metroid Other M allegedly breaking canon with the rest of the Metroid series, however I used more images than Reddit allows on a single post, so I had to resort to posting a link to Blogger.
I address common claims about Other M breaking canon, such as:
"Other M calls Space Pirates "Zebesians" even though Prime 3 shows their Homeworld isn't Zebes"
"Other M says Ridley can't lead the Space Pirates even though past games said he's their leader"
"Other M's Queen Metroid shouldn't exist, as a Queen could only evolve on SR388 or a replica of its environment as seen in Fusion"
"Other M acts like the Prime series didn't happen when Samus says she hadn't worked with the Federation since leaving them"
"Samus being scared of Ridley makes no sense considering she's fought him several times at this point and had no issues. Maybe this could've worked as a prequel, showing her first encounter with Ridley, but not this late in the timeline"
Etc.
I use many links, images, and gifs to cite the sources of what I say (e.g. "Zebesian Spaces Pirates had been called "Zebesians" since Super's manual")
