I don’t think keeping trans men out of sports as a form of protest would actually do or change anything. Like I get what you're saying & I wouldn't have done this myself, I also don’t think the rhetoric in the sports industry would actually change if he didn't join. Like, you could be blaming the cis people who write the rules that exclude trans women (and often trans men btw, there's a reason he is on the women's team) instead of other trans people
it’s not about it being a “form of protest”, it’s about being complicit in a transphobic system. by participating he’s validating a system of sex-segregation. it’s not uncommon for people to make the argument that it’s not transphobic if someone is discriminated against based on their sex, not their gender, or that it’s not transphobic if someone is discriminated against based on whether or not they medically transition, not their gender. yes, cis people made the rules. he chose to play them.
