Re: marketing hype
Recently a tracker blocker I was using on (desktop) Firefox was removed due to it being flagged up for malicious code. I do use some security plugins to block ads, trackers and other things (in addition to the tracker blocker in Firefox) but the irony is it’s hard to completely trust these plugins aren’t up to no good or have been compromised in some way.
Phones and tablets are more at risk because although we can use privacy browsers to (hopefully) block ads and trackers, apps have no privacy settings at all and are totally open to data mining and tracking.
