The way I see it, this is a small downpayment on the debt we have built up so far. Internship
programs like LF Outreachy to get more underrepresented groups involved in open source are trying to 
change the open source community culture to be more inclusive, but simultaneously rely on the culture
being welcoming enough as well.

I do see the challenge involved in preserving the changes and ensuring no new code is added with
outdated nomenclature (but see [1]), but culture changes one person at a time, and I'd encourage the community
to do the work needed so we can move past our (mostly) inadvertent role in perpetuating it.

That's my 2c (or your sub-unit currency of choice).
