This is one of those arguments there 90% of the time the people are using the same word for different things.
The ones who are fine with it mean it in the most general sense (i.e., any sort of one-sided relationship, basically any celebrity fandom falls under this and arguably so do fictional ones.)
The ones who say it's bad are referring to a subset of that, the ones who are delusional enough to think a vtuber is their actual friend/romantic partner (something that isn't healthy for you OR them.)
There's occasionally someone who thinks all one-sided relationships are bad (and is probably weird about say, kpop stans and actor fans as well) or people who think "No X-chan really is my girlfriend, fuck you", but those are both unusual.
Basically: Parasocial relationships are fine so long as it's not an unhealthy one, but some people started using the word "parasocial" to refer specifically TO the unhealthy ones and made everything confusing. Just don't be a schizo and it's fine.
