I see your point. But in the Amazon culture, your word and opinion were always considered subjective. And you were always expected to provide data to backup any opinions and to Earn Trust.

One middle ground is to offer the interpretation and then in parenthesis offer the data to justify it - I used this a fair bit. That allowed me to express my personal opinion, often as a subject matter expert, and make it possible for the reader to skip the data if they trusted me, but also have it available for people who didn't buy into my interpretation and wanted to do their own dive into the data.

The problem at the end of the day is you are willing to accept "many" and "happy" there's an implicit trust that you need to have of the writer. If I don't know the writer, I don't have any data points to prove to him that their definition of "many" and "happy" are anywhere aligned with mine. I think I was less likely to worry about reading the data when I was reading from trusted sources, engineers I worked with for a long time. But if I didn't know somebody, I was never willing to just give them the benefit of the doubt they had done the proper research. You'd be surprised how many people do NOT do ANY research!
