Since Cursor bought Supermaven, why I can't I use it in Cursor?

Hello, I couldn’t find a better short description for my question.

Since Cursor bought Supermaven, why Cursor tab allows for much less usage in free tier?

I mean, I switched to Cursor to use all its features including tab completions like I did on VsCode before with Supermaven.

I can’t afford Pro right now, so when free usage ends, I get a VSCode fork with no AI features at all, until the month changes.

Why not include a Supermaven like experience in the free tier and charge for the extras?

I can already use tab completions for free using Supermaven on Vscode and I don’t say that this should change at all.

It just seems like an odd decision by Cursor to operate like that.
What do you think?
Thanks.
