Hi @dotcoma, as @Manoj mentions, we don’t modify apps we publish, for many different reasons as it is neither our focus, nor our role in the ecosystem.
But we inform you and give you a chance to be in control with the privacy score in the /e/ app store and the list of trackers featured in apps.
As highlighted in this research from last year, the problem with the FB SDK was linked to the Facebook Login. So if you want to protect your privacy in your apps, you probably want to avoid apps with Facebook Log-in trackers or similar. And if you check the trackers list in your apps, it is likely you will see Facebook trackers in a lot of apps!
Regarding your question about blocking trackers, this is a different ball game and we plan to launch a solution to deal with that next year as highlighted by Gaël in his post here: /e/ Mobile OS Next Steps & A new roadmap for 2020
“In 2020 we are going to introduce new features that will let users know in real time how much data is leaking from installed apps, and how to block the corresponding trackers. It will also offer a synthetic summary of these activities over time.”
I hope this covers your questions.
Cheers.
