This is completely fine, as those are your own installs, but LLMs can't be owned by the users, your Opus is the same Opus as everyone else's, your only difference is the suscription tier to their API.
If you had your own on-premises LLM, that would indeed be your LLM, and it would make sense to compare it to the on-premises LLMs of other people, as your setup particulars would affect the result.
The copyright to the Outlook binary isn't owned by the users either, even if they're running it on local hardware. The Opus 4.8 weights are (we assume) the same between users, but the conversation/tooling state is not shared between them by default. I prefer to route around this construction myself, since I do think there's some ontological slippery-slope potential, but from a lexical perspective I think “my” is a perfectly defensible abbreviation in context.

There was a time where one actually bought software to own it.
This time is.. actually it is right now. Please leave at once.
