As per my previous posts in this thread, while I understand people who are upset with Blitz being a paid feature, I think it's important we don't get carried away emotionally and assume that this was done because Paradox likes making people unhappy/is in it for the cash. There's a huge amount of evidence to suggest otherwise, from the free DLC that was bundled with EU4's rights of man (or the Polish DLC with HoI4), to Podcat spending a not insignificant time on his weekend looking at posts in the suggestions sub-forum (drop in there if you don't believe me - you'll see Podcat has dropped into a bunch of threads - even if he reads twice to three times as fast of me (I'm a bit of a slowpoke - I couldn't read as many threads as he did if it was an eight-hour-a-day job) that's a fair bit of his free time he's spending being in touch with the community. He's also made 188 posts in the main HoI4 forums (Steelvolt has made over 200!) This isn't really the behaviour of a "screw the consumer, I'm just going to paywall and take their money" kind of developer.
I've been gaming for many, many years, and when I was healthier, used to play many different types of games. Paradox is in a class of its own when it comes to developers of its size looking after its community. Yes, it still needs to pay its staff and make a return on investment, but it's a long way from greedy or exploitative. It won't always do things we agree with, and like all of us, will occasionally make mistakes, but I don't the evidence available supports calling Paradox greedy or cashgrabbing.
Also, as many others have posted - we don't have a 'right' to free anything (particularly in the context of stuff from a video-game developer - I don't want to get into basic human rights and what-have-you, that's a different kettle of fish

). The only reason we have any expectations of free stuff at the moment is because of PDS' behaviour in the past (ie, they regularly include free stuff, and good amounts of it, in patches), and have a long history of doing so. I'm not saying it wouldn't be good PR to include Blitz on the free side of the ledger (personally, noting I have virtually no experience in marketing and very limited experience in consumer relations, so my view should be taken with liberal amounts of salt, I think it would), but we are not being treated badly if it's on the paid side.
Did you maybe consider that the people who make portrait art might not be the same people who are fixing core mechanics? ( So how many portraits they make or don't make have nothing to do with how fast other things can be fixed ).
Or would you prefer if Paradox's 2D artists were tasked with fixing core mechanics? I know I would not!
Your lack of faith in Sideburnout's engine coding abilities has been noted

. Although, being serious, I totally agree - sorting the engine, or fixing scripting issues, or doing 3d animation is whole 'nother set of core skills to 2D art (although I'm not saying Sideburnout and the other artists are one-trick ponies, but I think it would be a bit rough to expect them to be able to do everything!)
