I've also heard that in Alan Rickman's final scene, the director called for the release of his harness early (as in hitting the quick release on the 1 of a 3-count). As a result, the look of fear on Alan Rickman's face is genuine. From Rickman's perspective, the stunt initiated unexpectedly.
If true, another bit of realism appears right there on Rickman's shocked face.


It's been a steady exodus since less than a year ago when they removed the bit from their TOS about never selling your personal data and promising to protect your privacy.
I believe the recent surge has been the forced integration of AI features which are on by default (arguments were made to at least make them opt-in and not opt-out). Such features compromise privacy and security.
They're actively doing everything they can to monitize the consumer and going against their supposed stance as the 'privacy focused' browser.
