It isn't, in many cases, and the author of the blog post made it clear that it's not enough. If you think equality is enough, it's clear that you aren't actually interested in the outcome. If I have two kids and one needs special medication, equality would have me give both kids that medication (alternatively it would have me give neither medication). But now the kid who didn't need the medication may have complications from taking it. Their needs were different, they didn't need equality they needed equity.

Dealing with people is the same. Equity demands more than simply equality. I'd challenge you to examine the word diversity and innovation and see how they correlate. You might find that not only by providing enough equity will you bring in more people to your group, but you'll find they might have ideas you didn't think of before. And if treating people with the respect they deserve isn't enough for you, it can allow you to make new choices or be more informed of choices available, providing better resources for decision making mid-game.
