What value does "strictly speaking" bring to the discussion?
So that you don't have to address any of the issues?
Because DRM is primarily used to ensure the content is not shared in a way the owner does not allow. That is not what SynthID is doing. All it does is allow people to know it is a generated image specifically for when it starts to be widely shared on the internet.
So strictly speaking brings a lot to the discussion when you actually think about it. Stating that DRM != SynthID is addressing issues where people seem to think that DRM == SynthID. Those people are wrong, and strictly speaking need to be corrected.
Accuracy is valuable.
Words matter? DRM means digital rights management, not simply any kind of metadata a person doesn’t like.
