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?
Doesn't seem reasonable to compare how you feel about open sourcing personal projects to open source software that a company builds and relies on for revenue. Open source is amazing because it allows all of us to share knowledge and build things better than any of us could build individually, and I LOVE that. When a goliath like AWS comes along as abuses OSS to make money off of someone else's work without contributing back (either with money or code) they're not operating in the spirit of open source and they're potentially making it more difficult to successfully run that company (which IS contributing software to our community). That's not cool.
