Just fyi, every company is legally obliged to work with law enforcement. It's strange that people think that a company can just refuse court orders. The point and benefit of companies like proton or tuta is that there is very little information they can actually give and they are fully transparent with public when and what they were obliged to give. It's funny that when company hides this, like telegram, who worked with law enforcement thousands of times and handed over stuf like non encrypted chat messages, they are seen as private and not disputed by their users. But when company like Proton writes blog posts about the cases to be transparent and what (little meta) data they gave, people are out of their mind calling them out for it.
