I don't recall 2s latency, but do remember 0.25-0.3s latency one way for transatlantic phone calls in the 90s, which happens when the call got related over geostationary satellites rather than over Atlantic cables. It was basically a 0.5-0.6s roundtrip delay enough to cause you to talk over each other.
It only happened when there were too many callers at the same time. The solution was often to redial and hoping you ended up with a non-satellite call.
Agree - I read this as it will be easy to replace the battery when it reaches its end of life and no longer can hold my charge. It will still take time to replace it, but that's okay since it'll only be done once every few years. It's not meant to re-introduce swappable battery packs, so you won't be able to carry spares on long trips etc.
The copyright holder can set whatever license they want, including writing their own.
In this case, I'd interpret it as they made up a new licence based on MIT, but their addendum makes it non-MIT, but something else. I agree with what others said; this "new" license has internal conflicts.
It's humbling to know that the RAM of computers like ZX Spectrum and Commodore 64 would fit in a single IP packet. It took minutes to load that "paket" from cassette tape.
Another way to donate is to proof read documentation and report on typos, spelling errors, etc. Some projects have documentation in multiple languages - helping out in a language you know is another excellent way to contribute.
Many projects have great communities, making it all fun and engaging.
