The new EULA and commercial add-ons

I asked the following on the RSC Facebook page, and would be interested in how else clause 9.2 (i) could be interpreted.
'Does the new EULA mean that from now on only RSC will be able to create and sell add-ons for TS2013 - paragraph 9.2 (i) appears to prohibit anyone else from 'commercial gain'.
9. USER-GENERATED CONTENT
Please read this section carefully before creating or making available any user generated content for the Software:
9.2 Any UGC which you create or make available to other users (even if the UGC you make available was not created by you) must agree to and comply with the following terms and conditions to the fullest extent you are legally able:
(i) The UGC must be designed and used for personal use and not for any business purpose or for any commercial gain;'
After not getting a reply on Facebook, I emailed the same question to RSC support. I then had a reply linking me to a May Facebook posting which referred to editing RSC content. I emailed again pointing out that I was asking about third party original content, and I immediately received this reply:
Alan,
I have spoken to one of our board members, who has come back with this:
Thanks for letting us know your concerns about the TS2013 EULA. We updated this in TS2013 in the hope of making it clearer than the old TS2012 version. The clause in question is trying to protect assets owned by RailSimulator.com from being repurposed and sold on without our consent. We will discuss this clause with our legal advisors and see if we can make this cause clearer in an updated version of the EULA.
I hope this answers your query.

From this, it looks like they are not trying to shut down third party commercial operations - however, the damage has already been done in the US with SMMDigital withdrawing from producing add-ons for TS2013, and others talking about doing it.
