An anti-vaxxer does have a choice, but so does the society around them. If you do not vax you run the potential of carrying a larger load of a decease that can harm and/or kill me and/or my family simply for having been in the same space as you. I do not want that risk and if enough of society believe that risk to be too great, then you, the anti-vaxxer, must vacate the public space.
Abortion is explicitly different as, for one, it doesn't physically effect any other human being except the mother. Now, beyond my feeling that this question is quite explicitly a smug attempt at a "got ya" question, in the case of an abortion, the Mother is the whole of society, and, like in the anti-vaxxer case, the society gets to determine what's best for the whole... to be clear, that means the Mother has sole determination to whether to carry a pregnancy or to abort.
If your phone is Android... then the phone's operating system is "open source" ( for reference ). Also, the kernel of Android is Linux, which is, itself, an Open Source project.
Now, those are just the core systems that run an Android phone. Obviously not every app on the phone is Open Source. Most likely, not even the majority of apps are open source. That said, if you look into it, you'd probably be surprised to find far more Open Source apps on your phone than you think there are.
