I like when companies take criticism and go "k, that's valid we'll do better". Has that ever happened?
A few, from time to time.
Hideki Hayakawa apologized for firing Hideo Kojima. Hideki basically said that he doesn't know much about video games, and that his job is purely to make profit with mobile/gambling products. Which is probably the most brutally honest apology I've ever read.
On the Japan industry topic, Eiji Aonuma said that he was very sorry about very little details in Ocarina of Times, such as having to go to the inventory for putting on/off the heavy boots. Incredibly humble from him, considering that it was one of the most loved games of its time. Still apologizes for the little details, because he wanted the experience to be perfect, not just excellent.
Paradox Development Studio usually listens to its audience and tends to the reported problems. Frictional Games' team has a blog, and interacts with its audience. They admitted when they didn't like something about the product, always listened to their audience and are very honest about their business plan. They actually show their financial results with their audience, explaining what's going to to pay the wages, what's for the next titles, and what to expect with these funds.
One of Bethesda's devs (can't remember who, sorry) actually apologized shortly after F3's launch, because of the complexity of programming functional ladders within the game, because of the multiplatform thingy.
Peter Molyneux apologized several times for promising too much with his godlike simulators. To his defense, Black & White may not have reached his own expectations, but I think that it was way beyond what the audience ever expected anyway. Guy seems very critical of his own work, when in reality, he still introduced something that was really, really new. Couldn't find Black & White anywhere on Gog or Steam by the way, which is a shame. I'd gladly give it another shot.
Square Enix also apologized for one of their Final Fantasy titles, I think. Couldn't tell more, I've never really been a fan of this franchise, but they seem to listen and care for the audience. They took risks with good quality reboots (Hitman, Deus Ex and Tomb Raider, mainly), and it seems that they tend to fix the problems with the new titles (example : the duck and move system from Deus Ex, which was widely criticized and is now fixed, apparently).
Mike Morhaime and Jay Wilson from Blizzard acknowledged many flaws of Diablo 3 and issued public apologizes, with promises of fixing them. Don't know if they did, though, I haven't played a title from them since at least ten years.
EA apologized for a vague reason, basically saying "We are not perfect, but we shit on the competitors, our DRM policy is the best, and we offered a free title to compensate some mess with simcity, so sorry for being unbent, unbow, unbroken" which is probably the very definition of a passive/agressive rant.
