Even as someone who declines all cookies where possible on every site, I have to ask. How do you think they are going to be able to improve their language based services without using language learning models or other algorithmic evaluation of user data?
I get that the combo of AI and privacy have huge consequences, and that grammarly's opt-out limits are genuinely shit. But it seems like everyone is so scared of the concept of AI that we're harming research on tools that can help us while the tools which hurt us are developed with no consequence, because they don't bother with any transparency or announcement.
Not that I'm any fan of grammarly, I don't use it. I think that might be self-evident though.
