Signal responds to warrants with all the the data they keep.

ProtonMail / ProtonVPN responds to the vast majority of warrants with the data they keep.

Apple iCloud always responded to iCloud warrants with whatever data they had (eg. If the user didn’t enable encryption). They shouldn’t have removed end-to-end encryption for the UK, but they have thousands of employees in that country and millions of customers.

Sometimes it’s not the company that is the problem, but the country / legislators.
