They said "Most other countries" and you replied with "Many countries"
"Many" does not necessary include "most" but "most" does include "many".
No, it doesn't. If a set is of sufficiently low cardinality, “most” (in extreme cases, even “all”) of the set may not be “many”.
Most-all, in fact—Catholic Presidents of the United States have been Democrats. But it is not the case that many Catholic Presidents have been Democrats.
Most women to have served on the US Supreme Court did so only after its first 200 years. But, again, there were not many women who served on the Supreme Court only after its first 200 years.
I replace the following sentence from my previous comment:
> Most other countries don't have freedom of expression and freedom of the press, so copyright law in a different country usually lacks a unifying exception test like fair use to supplement the specific enumerated exceptions.
with the following:
Copyright law in most countries usually lacks a unifying exception test like fair use to supplement the specific enumerated exceptions in each respective country.
The rest of my previous comment remains the same.
This is demonstrably wrong. Many countries have both freedoms, albeit some have less strong protection than others.
