It's not actually cost-efficient if you take into account one factor: demographics, or specifically: staffing.
A crew member of a train has a very demanding job. The shifts are highly irregular and you may have to spend the night far from home. In this regard it's even worse than flying.
Someone has to maintain the infrastructure, which by its very nature can also be in remote places.
Particularly busy railroad crossings also require staffing, even if they're ostensibly in the middle of nowhere.
Very few people in our ageing societies want this sort of life and you have to incentivise them to do it, which adds costs.
You cannot make the cost-efficiency argument without acknowledging all the costs which aviation and automotive travel externalize: air and water pollution, damage to wildlife, global warming, lack of walking/cycling infrastructure, rising sea levels... a disproportionate part of which are born by poor or faraway people who have no choice in all this.
Edit: forgot about noise pollution and about flooding risks (due to impervious surfaces like runways and parking lots).
I also doubt airfields and planes require significantly less maintenance than trains and tracks, but I have not researched that.
Bollards are good at preventing the inconsiderate from parking on the sidewalk. For fewer people to be killed by cars, however, you want transportation infrastructure which does not rely on having fast metal boxes in close proximity to pedestrians (or cyclists, wheelchair users, etc).
OK, I can see where they're coming from with things like Signal. Not that I agree, but at least I can understand the reasoning behind it.
But what is uBlock Origin's sin? A law-abiding citizen is supposed to be OK with seeing ads, or something?
Can someone who reads French please elaborate on what the linked piece is saying about it?
The investigation partly relies on notes seized from the defendants which mention various privacy tools: GrapheneOS, LineageOS, Signal, Silence, Jitsi, OnionShare, F-Droid, Tor, RiseupVPN, Orbot, uBlock Origin…
According to investigators: "these elements confirm they were willing to live clandestinely".
According to the prosecution: "these notes consituted a real playbook allowing anonymous use of a phone, showing the person was willing to live in secrecy and hide their activities".

Students in France protested multiple times at least partly against Parcoursup, the government software where high school students enter their choices for higher education and get selected by universities.

> In the past few months, several high school student unions have called for protests against recent reforms in France's education system.
> They have also been protesting against 'Parcoursup', an online government platform designed for selecting students for university.

Wow that is amazing! His proposal for "IPv4+" is... I have no words. Thanks for the laugh.
