4.6 Font Software. If the Software includes font software […]
(b) You may embed copies of the font software into its electronic documents for the purpose of printing, viewing, and editing the document. No other embedding rights are implied or permitted under this license.
(c) As an exception to the above, the fonts listed at http://www.adobe.com/go/restricted_fonts are included with the Software only for purposes of operation of the Software user interface and not for inclusion within any output files. The listed fonts are not licensed under this Section 4.6. You may not copy, move, activate or use, or allow any font management tool to copy, move, activate or use, the listed fonts in or with any software application, program, or file other than the Software.
The link http://www.adobe.com/go/restricted_fonts is now defunct, as the correct link is now http://www.adobe.com/products/type/font-licensing/restricted-fonts.html. Here it says:
If the Adobe Product EULA limits your use of certain fonts to the operation of the Adobe Software only, the following list identifies the fonts governed by those limiting EULA terms. […]
As I understand it, the license agreement is quite clear. "You may not […] allow any font management tool to copy, move, activate or use, the listed fonts [= Minion Pro] in or with any software application, program, or file other than the Software [= Adobe Acrobat]". But this is exactly what the
minionpro package does, as it is a package containing scripts which "convert the Open Type to Adobe Type 1 format".
In the license agreement for previous version of the Reader, which is Adobe Reader 11 from 2012, the same content as section 4.6 is given in section 16.6. This agreement is located on Adobe's archive page.
The files for the
minionpro package are from 2007, when the concurrent version of the Reader was version 8. In the license agreement for that version, it appears as if the
minionpro package was unproblematic given section 14.7 (I can't copy text from the agreement, so I'm just quoting the relevant sentence here):
You may convert and install the font software into another format for use in other environments […].
There is no mentioning of "restricted fonts" in this agreement.
So am I right in concluding that the
minionpro package was an unproblematic package in 2007, when the license agreement allowed conversion of any fonts bundled with Adobe Reader, but that it is more unclear now whether the package should be on CTAN, given that the license agreement now states that one cannot use any tools to "activate or use" certain restricted fonts, of which the bundled Minion Pro fonts are explicitly included?
I wanted to address this to the package maintainer, but no contact information is provided in the documentation other than a now defunct url.
