Not in the fullest sense. It can be turned off (for now), but its behavior once enabled is subject entirely to Microsoft’s whims.

Full user control is what you’d have if e.g. you were running a FOSS Recall analogue powered by the local LLM of your choice on some flavor of Linux. That setup will only ever do what the user intends it to and barring supply chain exploits, cannot go rogue.

The behavior of Windows is subject to Microsoft's whims. Microsoft could just as easily have pushed an update to Windows XP that exfiltrated sensitive screenshots too. The existence of a user-facing feature changes nothing at all here

See again: Raymond Chen's "other side of an airtight hatchway" analogy. Microsoft already have ring 0 access to your machine

> That setup will only ever do what the user intends it to

There are tons of times I've had stuff running on a Linux box do things I didn't intend it to do. Often even with software I wrote!

I guess you're one of those people who only ever writes perfect code that exactly does what you intend the first time.

Alright, let’s rephrase it to be a bit more pedantry-proof: A Linux-based FOSS analogue of Recall built on a self-hosted LLM of the user’s choice will never actively undermine the user’s privacy or sell them out as long as they’ve vetted all software involved.

There’s always the possibility of vulnerabilities and exploits but that’s not the point.
