@Gas,

The question is not about accepting or not accepting changes.

The question is: should the changes be pushed to your site without giving you an opportunity to back up (hence to be able to rollback in case of problem).

This is where opinions differ; the core team thinks it's better to automatically apply the updates while a lot of voices are against.

The motivation of automatic updates is clearly to address sites with poor maintenance.

A suggestion could be to instate a grace period during which the notification of updates would be displayed (as it was before) and dedicated admin could backup and update their sites. After this grace period, the updates should be automatically triggered
