I am quite sure it is not legal. Here is the distributing rules even if they had applied for a license:
2.2 Distribution. Distributor may:
(a) Make one copy of an image of the Software on a Distributor computer file server for the purpose of
downloading and installing the Software onto computers within Distributor's Intranet, for internal use only;
(b) Distribute the Software on a standalone basis only on physical media (such as CD-ROMs, DVDs,
hard disk, etc.); and
(c) Distribute the Software as a part of or with Distributor Product or Distributor Service (i) through
electronic means such as electronic download-- including, without limitation, electronic software
download-- for example bundled in Distributor's installer, which in turn, is downloaded through the
Internet and (ii) on physical media (such as CD-ROMs, DVDs, hard disk, etc.).
In all cases the Software is to be distributed in complete form and only for purposes of complete
installation and use by the end user. The Software shall not be configured or distributed for use without
installation.
So even with a license, you can only distribute it to be installed and not ready for use. That is, unless they made a special deal with Adobe.
