So basically this article is 50/50 insightful and helpful feedback from a Framework customer, mixed with gripes by someone who bought the wrong laptop for them. Part of the reason this is getting a sour response is that most laptop companies don't even offer the choice of a larger, more expandable model. Framework does, and you bought it despite not actually wanting that, then dinged it for the compromises inherent in the design you chose. It seems like the 13.5" Framework was the obvious fit for your needs?

To use a silly food analogy, imagine there's a popular salsa company. The customer base has been clamoring for them to release an extra-hot salsa that also has corn in it, though that's a polarizing combination. A purchaser gives it a bad review because, in addition to some very legitimate critiques of the spice flavors, it's too hot and corn doesn't belong in salsa. People who wanted the extra-hot salsa with corn have a point when they say that person should have reviewed the medium salsa without corn.
