in many of the F500 orgs I've worked at -- yes it is. unambiguously so.

diversity / inclusion / team building activities were explicitly called out as part of yearly goals and performance review metrics.

things like go to a women-in-tech event and just listen, or a black history month discussion, read a book about homelessness and minority communities, etc. I went on a postmodern literature spree and ended up reading a bunch of african and middle eastern authors and that qualified for the perf review.

the "LBGTQ 5k" is a laughably bad strawman and would never be required for a bunch of reasons.
