I just looked over it, but there were various reasons. Some were about the understanding of certain lore, like how real a simulation can be to be tiered as an actual construct and what is its actual scope, others were about having to accept certain elements of worldbuilding that directly limited any statements to certain levels (Like one that claimed that any usage of infinity was a metaphor for something that is beyond your ability to count, but that actual infinity does not exist, so most statements that mention infinity should be understood as "something very big that you can't comprehend"), and other stuff.
With HSR, I don't think any attempts to downgrade would go this deep since some feats are very clear in lore (Like the beast Dan Heng defeated that could eat whole stars), but I can expect the usual "downgrade attempts" for feats that feel too big, like galaxy destruction on the grounds of "it could take years until they destroy one" or "even planet destruction can be seen as too powerful, there's no way they all scale to galaxy".
I do think that some stuff can be easier to defend than others, but if I were even to compare to the average understanding of HSR, I wouldn't be surprised if most would be against such scaling (I remember some thinking it's unbelievable to think the Xianzhou Luofu can do anything close to destroying a planet)
