Updates are only good when you want them. In your case, it was a plus for you. AT&T would constantly push updates to my phone. I could decline them but it would eventually do it anyways. I needed to make a phone call one day and it was temporarily locked due to an update from the carrier. Too much control over my phone.
With the oneplus, I can control what I want my apps to access. You'd be surprised of what apps can access on your phone.
Well I too avoided updates because sometimes it would make my old device slower or buggy so I totally get that - but I never thought they were Mandatory with a Capitol M. I just drank the coolaid regardless and eventually trusted and gained from them.
