I know there alternatives but my problem is with the direction Google are taking Android and the fact they are abandoning existing open apps and replacing them with closed-source ones. More and more apps will not function either because they rely on Google Play Services, so trying to go around the issue by using OSS apps (such as through F-Droid) will only be feasible for so long, eventually Google will have so much of the API tied into Google Play Services it just is pointless to make an app without it. Google made a decision that its openness on Android is a strategic weakness, damaging potential revenues and user data acquisition. That's fine, I'm not crying over it, I am just going to leave the platform as soon as I can and go to something which is more open, such as Firefox OS (or possibly Jolla OS).
