What's wrong with Electron? Etcher is a tool with 5 minutes maximum running time, it's not Slack where you have to run on background for hours. Also size is irrelevant these days, you can download a 150 mb file in 2 seconds.
Definitely not the case for the majority of the world. Sure, it’s probably true for most HN readers, but many countries still rely on 3G infrastructure — or worse: satellite.
I remember spending over a week downloading Ubuntu 18, which also consumed ~10% of my monthly data cap for that single ISO. And before you make any assumptions, this was rural Ontario, Canada in 2019.
Objectively false - this matters for people with limited cellular data, in countries like Africa, on crowded wifi/cellular/satellite connections, with limited storage, and many other cases[1].
Where I live the average internet speed is around 30Mbps (even going as low as 15/10 in some cases) so that definitely isn't true, sadly.
