TBH, OP sounds like a bit of an entitled douche, edit: not the most appropriate descriptor, but I do think OP should try and look at the situation from another perspective.

In their blog post they complained about lack of transparency and noted numerous issues with Kagi that caused them to lose faith in the company. The CEO personally responds to explain themselves (i.e. make things more transparent) and OP sticks their fingers in their ears and acts liked they’re a victim because the CEO attempts service recovery.

I’ve made public complaints about companies before. I wish I received such tailored and personalised responses.
