As a Latino, I too am growing tired of the way some leadership and HR departments in tech callously, carelessly push and promote these diversity initiatives in a way that creates resentment. Combating racial bias is a sensitive topic. You'd have to be living under a rock to not know that. And yet companies continue to make statements like this without the tact it deserves.
Let's give them the benefit of the doubt, and say that they really were trying to fight inequity in the system. Instead of saying something like "Historically layoffs in tech have disproportionately affected minorities, pregnant women, and older employees. Here's a link to a study showing that data. With these layoffs we ensured that no group was affected unfairly", they just throw out the term anti-racist, and let the audience draw their own conclusions.
Because at the end of the day, making sure their layoffs don't unfairly target X or Y disadvantaged group--or really any group--is just doing the right thing. Why brag about the fact that your HR policies are not systemically flawed? It's as if you came home to your partner and proudly stated that on your drive back home you did NOT run over any elders or toddlers with your car. You're expected to do that. If anything taking credit makes people wonder.
In this case, it comes across as virtue signaling by Twilio's leadership. The same desire to curry favor when laying off people that makes CEOs tell their employees how hard the decision was for him or her. Trying to pat yourself in the back while announcing layoffs seems wildly tone-deaf to me. And at the expense of the groups they're allegedly trying to protect.
