The keyboard (and ports) will probably hold up a lot longer than the compute power of the Pi 4, so being able to swap out the internals without throwing away the perfectly good chassis would be a nice win for e-waste.
If you are not against the oppressor, if you are okay with allowing oppression to continue happening for any reason, you are on the side of the oppressor. You cannot be an ally from a neutral position, you need to pick your side and commit.
This is why if you want to be an ally to people of color it's not enough to not be racist, but rather you need to be anti-racist. We're seeing more and more how neutrality is dangerous in allowing systemic issues to exist and flourish (see elected Democrats in major American cities, the "not racists", allowing the police state to exist and perpetuate systemic racism). If you want to be an ally, you need to become comfortable admitting that the privileged position of neutrality isn't compatible with allyship.
The easiest distinction between activism and bigotry is to tolerate everything except intolerance itself. Activists mostly fight for more rights/freedom, and bigots mostly look to prevent that. It's not a perfect boundary, but I've found it works well for the significant majority of cases.
This looks super cool, I'm very interested in trying it. It looks like the link to the Firefox extension is broken though, is there a workaround to install the extension?
