Add all-adopters config, untruncate comparison group, shorten title, add access section

all-adopters holds the full 14,697 detected adopters. The comparison group is restored to its full 10,938 rows now that neither side needs truncating. default is unchanged for existing users.

+`default` is kept for anyone already loading this dataset. For analysis, use `all-adopters`, because `default` is cut by website popularity and that cut is not neutral: it leans toward organizations in the United States and Germany, and toward government, retail and healthcare, relative to the full set.
+
+Coverage below is for `Lets-Encrypt.csv`. It is a little lower in the full set, where `Year Founded` is 68.4% and `Locality` 78.6%, because less popular websites carry less firmographic detail.

 ## Comparison Group
 
-`Commercial-CA-Comparison.csv` holds 7,138 large organizations that were found using a commercial certificate authority and were not found using Let's Encrypt. It is there so the adopter file can be measured against something rather than read on its own.

 ### What the comparison supports
 
+Compare it against `all-adopters`, not against `default`. Both are complete populations under the same filters. `default` is truncated by website popularity, so comparing it to this file would measure that truncation as much as anything about certificates.
+
 It supports asking how Let's Encrypt adopters differ from large organizations that buy commercial certificates, across industry, country, size and founding year.
 
-It does not give an adoption rate. That would need a denominator of all large organizations, which neither file provides. Any percentage computed by dividing one file by the other is meaningless.
+It does not give an adoption rate. That would need a denominator of all large organizations, which no file here provides. Any percentage computed by dividing one file by another is meaningless.
 
 Organizations can use more than one certificate authority. Those found with both Let's Encrypt and a commercial authority were removed from the comparison file, so the two groups stay separate at the cost of not representing mixed estates.
