Do you have a link or something where they said they were against this sort of thing? I think maybe the only thing they really despised was the fact that when they were a small-time company they weren't able to get in on the DLC milking themselves. But now they can, and they do.
As late as 2010, Paradox was still mocking paid DLC from other game companies, e.g. Civilization V for requiring players to
pay for a Babylon civ DLC, in response to which they jokingly
added Babylon as a country in Victoria 2 via a patch. Paradox games were always bug-ridden upon release, but Paradox not only patched as many bugs as possible in numerous free patches after the initial releases of their games but also added non-trivial amounts of features and content via the free patches, and they looked down on the business practices that were becoming common in the industry. There were numerous posts from Paradox employees to this effect in their own forums, many of them in the publicly-accessible parts, though I don't know how much of their old forum content is still around today. Certainly, by 2010 Paradox had already declined in many other respects, but it's still a bit astonishing to see how decline spread to their business practices to the point that they've become just another shady publisher milking their customer base through DLC.
