Because history is history. Facts are facts.
If only things were that simple, life would be easier!
As the old joke goes "In Russia, how can anyone predict the future when it’s so hard to predict the past?". Examples: https://www.pbs.org/redfiles/prop/inv/prop_inv_ins.htm
Thanks, I enjoyed reading it all.
I didn't realise that 'photoshopping pictures'/airbrushing, was actually done/used a lot, a long time before the internet/computers, were commonplace/existed.
They do say, "History is written by the victors".
Anyway, history is often/usually very much an interpretation/speculation, of the 'facts'.
E.g. (factitious, made up example) Was this wooden gear shaped thing, from thousands of years ago. An artwork, early computer for calculating the moon phases, religious artefact, or simply a child's play toy ?
Back on topic, and being rather cynical. I think what is really happening, is as follows:
A boss of a giant entity, is considering the recent racial tensions.
Do they really/properly address the situation ?
I.e. Make sure their workforce is (locally) racially diverse enough, and racially fair, to everyone ?
Total Cost $10,000,000,000+, and annoy hundreds of thousands of otherwise, happy employees, and maybe an inconvenience for a billion customers worldwide and annoy many shareholders (maybe), with any disruption and extra product costs, to recoup the cost.
Or (they always hated the horrible IT department, anyway), do they say "They have just ordered the IT department to ban/remove all references to master/slave, from the companies software" ?
Total Cost $10,000 (<), and annoy the 10 people in the IT department, and around none of the customers, would be annoyed.
tl;dr
I think the announcements of "We are now removing all master/slave refences from ..", to be a cynical attempt (pretence) of taking anti-racism action. Purely for publicity reasons.
