Why don’t the Lineage OS users of this show use microg version of Lineage instead of G-apps for improved privacy?
For example, where I live openstreetmaps/ OsmAnd is not well mapped and updated. So, I am forced to use the proprietary google maps but the app works independently and without the need of having a google account. Also, you can get notified of updates via the RSS feed from softpedia.com of newer apk versions and download it from their website.
I use Signal app similarly too which is unavailable in the F-droid store and is dependent on google-play services.
