I don't follow what either you or the OP are upset about. Where is the apologism and why do you think it's needed?

Kagi rolled out a free feature to its existing customers without increasing the price of their plans. The limits of that plan seem quite generous, as well. The only way I can make sense of the OP's post is that the OP wants the Kagi subscription price to decrease. Perhaps that's fair, but it doesn't make any sense here because you're strictly getting more for your money. If you're paying $10/month for a subscription, yesterday you couldn't use Assistant and today you can for the same $10/month. Placing a cap on how much you can use seems quite reasonable given the service costs money to operate. If you choose not use it, you're no worse than you were yesterday... you can happily go about using the search service you were already paying for.

Is the problem that the free usage isn't unlimited? Is it that not using the free service doesn't reduce the search price? Or is it that those using Assistant more than you appear to be getting more value for their money? I'm not trying to be dense, but I really don't see what's even remotely controversial about this announcement.

Lately, every subscription I have is increasing the fee without giving me anything. Kagi is giving me something extra without charging me any more money. I'm sure the nefarious intention is to make their service more attractive to non-subscribers and grow their userbase, but interests can align.
