I'd say "taking from" is similar enough. It's still insinuating that straight people are being deprived of that character. He's still asking why people who want diversity have to take from his side, so to speak.
Even the idea that diversity isn't a zero-sum game is slightly flawed. There are only so many slots open, so only so many characters can be used. For every slot filled by a straight white male, that's one less slot that can be filled by women, people of colour and LGBT people.
This becomes a problem because writers want to use the characters they love - the characters they grew up with. And the characters they grew up with were straight white males. Those are the characters every writer grew up with, because those were the only characters that existed. And still today, those are the characters who get the most focus. Today's young readers are still growing up with the same damned characters from 50 years ago, so today's readers are going to grow up to write those characters, and nothing will ever change. Unless a conscious decision is made to say, "No, to hell with that."
People who grow up with Sam Wilson as Captain America, seeing him in multiple books every month, are going to care about him more, and are going to have their own Sam Wilson stories they want to write, rather than just re-writing the same damned Steve Rogers stories we've gotten again and again and again. People who grow up with a gay Iceman are going to want to write stories about Iceman dating a guy.
It's a long game, which is what makes it important to start early, and to not stop playing it.
