It's "worse for humans" in exactly the same way that first the Industrial Revolution and later computer programming made things "worse for humans", but the post you're referring to only notices that it's "worse" when they are the victim.

It’s “worse for humans” in exactly the same way the Industrial Revolution was bad for all the horses that weren’t needed anymore.

I agree with this actually. All of these things were good for some and bad for some, and these groups overlapped. All were good for (most) humans-as-consumers, and bad for (some) humans-as-producers, and the IR was also bad for horses.
