I think the thing is, at the top of a big corporation yeah they don't care. But the boots on the ground people who apply for a DEI or outreach type job? My experience is that they absolutely do care.
I did bike to work one year. Big group of us all at different companies/school. We stopped at Oracle on the way, because they had a big bike to work party. Now, I suspect Larry E. doesn't give a shit about me or my bike. But the people who put that on absolutely cared about the cause, about making people feel welcome, and overall, having a good time (I don't/did not work for Oracle).
The corporation doesn't care about you. But there might be some people who work there who do.
