I haven't made any moves away from Apple yet, but I'm cautious about upgrading because it isn't clear to me where the code for the scanning is in the current releases. They announced they were going to start scanning one day before the planned rollout, but it wasn't mentioned that an update was necessary so it seemed like it could've already been in iOS 14.x. I am willing to update to the newest version so long as there's still an opt out option by not upgrading to whatever version will include the on-device scanning. But if the code is bundled in already and is just dormant until some undetermined date then I'll be moving on. I'm not sure how I'll even know if it's safe to upgrade, but I'm hoping if there's any concern there'll be some news about it in the coming weeks.
