The License detection on the Package Overview Page generates a different license string than the download blocking.

PacakgeOverviewPage.cs - GetLicenseInfo()
IBrowsablePackageFeed.cs - CommonPackageInfo - GetBlockedMessageAsync(bool bypassFree = false)

To recreate this:

• pull SpecFlow 3.3.30 to ProGet
• add the license from the Package Overview Page
• Set the feed to block licenses by default
