I don't want to rain on anyone's parade, but you don't learn anything from this exercise. Unless you somehow know how many new customers would have signed up without a change in the price, you can't infer anything from this. It's tempting to compare with earlier growth rates (as the author did) but for a small, growing business the growth rate isn't going to be constant over time. What is really problematic, though, is trying to do this type of comparison when we're literally in a different world due to the pandemic.
I take your point generally but I think it's overstating it to say you learn nothing. Definitely the signal can be hard to isolate form the noise, but if it's a big enough signal you'll hear it.
For example: if sales fall off a cliff, it's reasonable to interpret that as "perhaps I over did it." and so on.

But (a) that's not the outcome, so it doesn't help here, and (b) with the pandemic, even if sales went to zero, you'd still need some way to know the effect of that.
Then it would be nice if you could suggest an experiment which would yield useful pricing results for him.
I don't know if this was your intention but it's kind of a pet peeve of mine when someone posts "that's useless" to a content creator without elaborating on how they would've approached the issue.
