S-off and cid- 11111111 enabled by default

I have recently bought a new htc one m8 which came with lollipop out of the box and yesterday I noticed that my phone is having s-off enabled and cid - 11111111 by default. I haven't done anything to my phone (no root access and bootloader is locked).... So my question is will I receive OTA updates in future? And is it good to have this options(cid and s-off) enabled by default. Pls help... 😊
