Two class-action lawsuits have been filed against Meta on behalf of Apple iOS users for allegedly bypassing their privacy preferences, Ars Technica reports. The lawsuits are based on the research conducted by former Google engineer Felix Krause, who alleges Meta sought to recoup lost advertising revenue by inserting a tracking code on external websites their users visited while using the in-application browser for Facebook or Instagram. The users who brought the complaint allege Meta downplayed privacy risks, disregarded iOS users’ privacy choices and tracked all activity on third-party websites. Meta denied the allegations in a statement.
