"I've removed my Master Password for now, just so my passwords don't get blitzed."
You may or may not know, but the reason this change is being made, is to get rid of "problematic" English-language nomenclature - the same function will be enabled by something called the "Primary Password".
(To be explicit, the undesirable connotation is with human slavery, where the word "master" would mean a master, sometimes owner, of slaves.)
Now, if I may, I will digress into a rant...
No-one can deny that racism exists, it can be casual, organised, deliberate, accidental, etc. I would hope everyone could agree that whatever adjectives are used, it's bad.
If we consider the deliberate and organised kind of racism - imagine the kind of people who post seriously and enthusiastically on /pol/ (8 or 4) - if they are "out", they may march at protests wearing swastikas, but more likely keep their activities anonymous - expressed online, and in the ballot box. One of their goals (and in the context, it seems obvious and reasonable) is to discredit their opponents - these could include almost the entire political left and centre, as well as most of the right and unengaged.
Now, the relevant part - one of their methods to achieve this goal (and this can be seen being openly discussed on some of their forums/boards) is driving a wedge between those who actively oppose them (a minority) and those who are uninterested, uninvolved, or even "normal".
Even assuming actions like removing the word "master" in favour of "primary" are taken in good faith in pursuit of a better, more equal, society: This is not what the majority of people affected by such changes will think. They will experience inconvenience, and if they make the slightest enquiry as to why, they will associate it with "those BLM people". They will be that little bit less likely to accept genuine anti-racist positions, and perhaps even drift into active racist thoughts and actions.
Don't assume I'm saying people will join the KKK over Firefox breaking their passwords - the point is that this is happening across society - both genuine and false-flag anti-racist positions and actions are being publicised (this could be as simple as some nobody sharing an absurd "loony left" story on facebook/twitter) with the intention of portraying good and necessary responses to racism in our society as extreme, and harmful to "normal decent folk". If this happens enough times, it will not be shrugged off as a one-off.
In nearly all cases of such "wedging" there will be no convincing evidence unless someone is willing to spend their time digging around the extreme-right web.
Please remember this if you are in any sort of position to influence any kind of change that affects others - by all means, take the actions considered necessary to improve society, but think hard on the effects, and how they could be presented - inconveniencing the uncommitted and denigrating the unengaged run the great risk of being nearly entirely counterproductive.
(Rant now ends - I bashed this out in the last ten minutes based on some previously unaddressed thoughts that pulled together when prompted by this master/primary thing Firefox is doing - please let me know if I got anything obvious wrong.)
