It seems to be the case, though: "Every account with an active subscription at the moment of the pricing change on March 15 will get the “Early adopter” status. This will make the special “Early Adopter Professional” plan available to them instead of the regular Professional plan, with the main difference being 1,000 free included searches monthly, instead of 700." Ref. https://blog.kagi.com/update-kagi-search-pricing#existing

Back in September they promised this[1]:

> If such change to Individual plans is to occur, we plan to grandfather-in all early adopters (meaning all current and future paid customers, up until this change) allowing them to keep their existing subscription price as long as they don’t cancel it.

My guess is that they will focus on the "subscription _price_" wording. Technically the price didn't change, since you can still pay them $10. They "just" changed the terms.

It's unfortunate since this is not what I (most people?) think when we hear "grandfathering".

Also, why do we find this out over a blogpost. Where's the email saying "oh by the way the your subscription is changing in a drastic way"?

They sent out an email last night, to me at least

Huh, must be just me. Mine doesn't seem to be anywhere, I have the product email setting turned on, and I get their billing emails. Strange.

Mine was in spam with a pretty high spam score.
