It's common well outside the tech sector. My (black) ex frequently complains how white people try to speak on black peoples behalf about what should offend her, for example.

To the point that she more than once have been in rage over white people accusing her (to her face) of being offensive to black people for saying something that they just assumed black people in general should find offensive.

She's also part of the diversity board of a major bank, where she sits on a panel that is mostly old white men talking about what issues affects their minorities and women, without a hint of recognition from any of them of the irony in that they've not recruited more minority representatives and women from their staff to be on the board itself.
