Yes they did.
And don't be rude and ungrateful, the lead developer on that project literally passed away less than a year ago, you're lucky you're still even getting this patch, most of the other studios would never update a 14 year old game.
Look at EA, they stopped selling Titanfall and Sims 2 because they don't wanna fix those games. Volition could've done that too, instead they're working their asses off trying to fix a game any other publisher would've threw out. But sure, they're evil and villains and whatever bad term yall can think of. They're a small studio, it took them 3 years to add Steam Workshop for SRIV, and that's without a threat of their studio shutting down if the next game doesn't sell well.
