Botspam killed blog comments, same way it killed discussion boards. Even if it's not link spam, the bots are using comment fields for C&C for botnets.
Besides that, I think there is a point in removing comments and interactivity in general. They hardly ever invite any interesting discussion. Comments are generally impersonal and low effort and invite a lot of shitty behavior.
If you have something substantive to say, respond in a blog post of your own.
If you have something personal to say, send an email. This is scary and intimate, but also permits you to actually talk to a person without the performative aspect of doing it in public.
