No, it doesn't, and even if it did: since utilitarianism is much more than "if you want to do something for other people, make sure it's helpful" isn't "utilitarianism reskinned".

But that's besides the point, because it obviously isn't. It feels like that's a hot take that neither cares to understand EA, nor understands utilitarianism and just operates on simplified versions of both. Much like people who understand the categorical imperative to be equivalent to the golden rule.
