Proton Mail Discloses User Data Leading to Arrest in Spain

This is a most excellent place for technology news and articles.
This comment is completely off the mark. The information that they disclosed is the recovery email -the same exact thing which happened previously- not any content of any email.
Also, proton does encryption with PGP, but you can't encrypt if the other side doesn't use PGP (which is the case for 99.98% of humans on the planet). If they do, proton supports this including with arbitrary clients using their bridge.
