It's not just the 'rainbow' initiatives, but the vague way those initiatives are described. Take this for example:
"These projects range from creating virtual support networks for LGBTQI+ individuals"What did they actually do here? Host a mastadon instance for gay people? How many of those people wouldn't have a chatroom with like-minded people if not for Mozilla's efforts? There are countless such spaces on the net already, for instance on traditional social media, on other fediverse instances, on discord or reddit, etc... so how much money did Mozilla spend creating yet another chatroom for LGBTQI+ people and how much real world impact did their effort actually have?
(Aside, saying 'individuals' instead of 'people' exemplifies the sort of swarmy weasel language used by cops, corporate PR, and other snakes putting on airs. Why do they do this, don't they know this kind of language betrays them for what they are? I guess they use this language to impress each other and don't really care that normal people perceive it as inauthentic.)
