I don’t think it’s necessarily a bad thing. Subtle but unusual is a good way to describe it.
However, I would like to point out that if it is their branding, then the character appearing is an advertisement for the service. It’s just not very conventional or effective advertising, but they’re not making money from a vast majority of implementations, so it’s not very egregious anyway.
True, but it you change the argument from “this will happen” to “this with happen more frequently” then it’s still a very reasonable observation.
