The vast majority of players have bought and played the sequel by now, but there are also still people who only own the base game, plan to buy TotK eventually, and want to participate in something Zelda-themed in the meantime without the risk of stumbling upon spoilers. And especially because so many people already play TotK, avoiding spoilers becomes harder by the day.
The community will recieve regular content updates, as I am a “reddit refugee” who saved and deleted nine years worth of OC stuff from the dumpster fire and I plan to upload everything again on lemmy.world instead: guides, art, memes, FAQs, etc. but of course contributions by other people are highly welcome. ;)

Honest answer: the official reason for that is the voice acting. It would be weird for characters to call him “Link” in cutscenes while the subtitles say Poopo.
…inofficially, that isn’t an excuse IMHO as there are easy workarounds. Dragon Quest VIII for example had LOTS of voice acting even outside of prerendered cutscenes, but most NPCs had nicknames for the hero. The subtitle might have read “Hey Poopo, how are you?” but the actually spoken line was something like “Hey, my boy, how are you?” …and then there is of course the option to just leave that part out entirely and just say “Hey, how are you?” without changing the subtitle. It wouldn’t have mattered what the player called their avatar then.
I usually skip through the voice acting whenever I can anyway, so it’s extra irksome.
