That's because you know how to find information in a computer quickly and precisely. Recalk is for clueless people. They can ask the computer in plain English.
Signal: Best data protection. They are on a different level from anyone else. They even reimplemented gif search through their app so it can be anonymised (instead of the data-collecting gif search in your keyboard). Just an example, they really try. Also has a desktop app that doesn't need the mobile app to be running. Downsides are google dependency (for push notifications - but they're empty, the encrypted data does never even touch google) and required linking to phone numbers. They do have usernames now so you don't have to give out your phone number to talk to someone. Behind it is an US based non profit - whether that is a downside everyone can decide for themselves.
Threema: No need for phone number, not even a credit card, you can buy it anonymously through their website. No google services required. Swiss based company, so much better laws than USA. Finance themselves through the one time fee of 2 USD and through their corporate offers, no nags for donations, no selling of data. Downsides are server code is not open source, and their protocol is less good than Signals, but still reasonably secure. They're working on a new one though. Also no independent desktop app yet (also working on it).
Your statements are inaccurate to a degree that they may as well be false.
Only 30% is gas. 70% is not gas. Renewables are growing extremely rapidly, now at over 25%. In the medium and long term Belgium is aiming to reduce its use of gas as much as possible.
Also, there are two nuclear power plants, not one.
Betting on gas, be it a stove or something else, is just stupid.
