Arc Raiders is playable in Linux, it got gold in protondb.
Path of Exile also got gold and PoE2 is platinum.
R.E.P.O is platinum.
That should make more than half of the top 10 games compatible in Linux. Unless it needs to be native for compatible, but I don’t have a problem with proton as long as it’s enough to select the latest proton version to be able to play.
Europe has an extensive passenger train network, but most of it is not high speed rail.
I looked on travelling from Madrid to Paris and it takes 2 hours if you fly (and then some time before for travelling from the city center to the airport, luggage check-in etc.), 11 hours with train and 13.5 hours with car. I think there are high speed rails between Madrid and Barcelona and in France, but still it takes that long time. The cost is similar.
Trains are really good but they have limitations, each type of travel has its advantages.
When I checked how long distance it was between Columbia, SC and Baltimore, MD I realised it was much shorter than Madrid - Paris. So I checked Munich - Paris instead which is only a 10 km longer than Columbus - Baltimore. It takes 7 hours with train and 8.5 - 9 hours with car. The flight takes 1 hour 35 minutes but the estimated time for travelling from central Munich to the airport, transfer time, flight, transfer and travel to central Paris is 5 hours.
They can’t, but that is not the purpose. If the chat control passes then all big services will be forced to leave EU or build in a backdoor. That will give them control over more than 90 % of the population and satisfies their goal. You and your friends are a rounding error. And if you would perform a crime, or are suspected of one, they can use the fact that you encrypt your messages against you.
