It's announced that the whole extension is going to be locked behind the Premium subscription. While I understand the need to make money, the costs are not reasonable for me and my usage. I also don't like your explanation that this is because of the rising costs of the AI-features, which I didn't need nor was convinced of to begin with.

You can circumvent this (for now?) if you set up your own server, but I think I prefer to part ways at this point.
