It sounds way less offensive to those who decry the original terminology’s problematic roots but still keeps its meaning intact.
I’ve seen ‘Active / Passive’ used, that seems alright. There’s plenty of alternative terms to use without borrowing terminology from sexual roleplay.
Anyway, the Sub is supposed to be the one that’s actually in control for this kind of thing (otherwise you’d just be in an abusive relationship), so that confuses things when you start trying to applying it elsewhere.
The issue is acronyms; there’s millions of products, schematics, datasheets, and manuals that refer to them as MISO and MOSI with no further explanation. Any new standard that doesn’t fit runs into the 15-competing-standards problem, and ought to be followed by an “AKA MISO” every time it’s used.
