i mean the yankee dude was already uploading his desserts online, he just wasnt gaining that much traction so its pretty understandable that a literal teenager would see this and want to help as its something he personally finds very cool
he wasn't getting traction because he wasn't trying to, no account name, no profile picture, no branding. he was basically just posting into the void intentionally, and the other dude very much had to convince him to put more of himself out there. people treat social media like personal blogs/catalogues of their own work very often and that seems like what he wanted to be doing initially. he's changed his mind now of course, but it doesn't seem like he started off that way
as a person who also has a hobby im very passionate about (in my case its arts & crafts) its just a lil annoying when people kind of insist on turning it into something to profit off of? or like show off? like what's wrong with doing things just for urself you know? anyways its not really that deep i just think akito's a bit annoying rn, but on the flipside i guess he seems like he's an idol trainee(?) or something influencer adjacent so it does make sense why he'd have this mindset ¯_(ツ)_/¯
