Apps, extensions should be taken down
Meshkov claims these apps and extensions are in the same position as the Stylish extension, which was
recently removed from the Mozilla and Chrome extension stores for secretly logging users' browser history.
Furthermore, the apps and extensions are also in clear violation in regards to the EU's latest GDPR privacy law because they do not ask for explicit consent to collect all this information.
Last but not least, the garbled privacy policies don't make it clear what exact data the extensions and apps collect, what's "personal" or "non-personal" data for Big Star Labs, or with who and how Big Star Labs shares this data with other companies.
Under normal circumstances, Mozilla and Google should intervene and remove these apps after confirming AdGuard's findings. The iOS app, which AdGuard first discovered pulling off shady tactics
last September but did not know it was part of a larger arsenal of intrusive apps, is not available on the Apple App Store, hence, Apple can't really do anything about it.
