Clause in the Valentina License

[Peter Alcibiades]

Thanks for the link.  I always read license agreements before installing, and 
came on the following:

"EXPRESS LIMITATIONS ON WORKS THAT CONVERT VALENTINA DATABASES. 

"If your Work includes the ability to extract data from a Valentina Database 
and then transform, translate or convert the extracted data into another 
database format, including, but not exclusive to the following formats, such 
use, unless allowed under a separate, signed agreement between You and 
PARADIGMA, constitutes a breach of this Agreement: mySQL (or its successor 
products), IBM DB 2 (or its successor products), SQLite (including its 
successor products or derivations from the source code of SQLite), Firebird 
(including its successor products or derivatives from the source code of 
Firebird), any open source database, Filemaker, V12, Access. The limitation 
in the preceding sentence applies even if the work transforms, translates or 
converts into an intermediary format of any kind, including any form of text 
or XML. Contact PARADIGMA to inquire about waivers of this provision."

What is this saying exactly?  

Is it saying that if I write an application in Rev using Valentina for Rev, 
and provide the ability for my user to export his own data, that he has keyed 
in himself, into csv tables, with a view to enabling him to use his own data 
as he chooses in a different database, and not be tied forever to a Valentina 
database, then I have violated the terms of the license, and he has also if 
he uses the export feature?

And with regard to me, the potential buyer, is this by implication asserting 
that Paradigma has the right to impose post-sale restrictions on the use I 
may make of the product?  That is, it can technically be used to do some 
things, but it is sold with a post sale restriction on use which forbids 
anyone to do them?  Rather like, to take an obviously absurd example, I take 
my Sony DVD player home and discover that by opening the package I have 
agreed not to play any but Sony movies on it?

These restrictions have been generally ruled unlawful and anti-competitive in 
the EU for obvious reasons.
