Think you might need a full stop there. OP might have a reputation amongst the "root/flash/ROM" brigade, but that by no means makes up all of their userbase, and user-blaming that it's your own fault for not randomly knowing about custom flavours of Android isn't really helpful.
This is consumer software, on a consumer product, by a consumer company, that's doing something that raises genuine questions about personal privacy and the access to information we give to hardware manufacturers. The default answer to all of this really shouldn't be "install random OS XYZ", in the same way that questioning Windows 10 analytics isn't "just install Arch".
I always used CM (or LineageOS) before the 5, they never completed the first setup once before I unlocked the bootloader, thereby reset to factory and I flashed a different ROM right away. Right now I'm on the stock ROM (and affected ofc) though.
Question time:
1) Do you use your camera? I had the feeling that everytime I went from stock to CM/LineageOS I lost features and quality.
2) Why would you pick "Sultan's LineageOS ROM" (not trying to slight Sultan, whoever that might be. I'm curious) instead of going with the official LineageOS builds?
