Context is everything. You're not gonna be killed by Unix command, enslaved by Github, and the land you own is not going to be confiscated by people who are writing an encyclopedia.
But IIRC, the first time I encountered the word "master" in computing, it was in the context of serial link data transfer, and there was a "slave".
The fact that a word can be used in the context of slavery doesn't mean the word always and everywhere carries the taint of slavery. What could possibly limit the reach of such a principle? Can I talk about how I like cotton shirts better than other fabrics, when the mere mention of cotton might bring some people back to an uncomfortable place?
I don’t think thats actually true. I think everyone knew the etymology was not slave owners. Which is the problem - its fighting a manufactured battle. Creating “systemic racism” out of thin air.
