He advertised it to a general audience on tic tok,and it is a service people pay for. Why would they not expect it to work? That makes no sense to me. It seems that way because you understand how dysfunctional email is. I would be upset if I bought a service for something I don't understand that is normally completely functional and free and when I relied on it it broke only for people who understand it to laugh at me because I should have just known that vendor was unreliable.

emojis break lots of things. Most people probably aren't surprised when using emojis in passwords doesn't work well either.
