The nature of subscriptions is that you keep paying for them forever whether you're eating them or not. Maybe you forgot about your sandwiches and they're just piling up on your doorstep.
Sure, but Kagi is one of the ones you'll get the value back out of. And if you don't use it you don't pay.
I only subscribe to Spotify, YouTube and Kagi as "online services". Video media I happily sail the seas for and I don't mind evil megacorps "losing" money on my behalf.
