I'm not on twitter, which is where this all started, so most of this information is coming from secondary sources.

The original IGN broadcast. Informative, but inflammatory.

PC Gamer article that links to comments made by other game devs, and the discussion by Xalavier Nelson Jr.

Game world observer article that links to the friends per second podcast and quotes Sven directly in his response to the issue.

video by Escapist Magazine which briefly covers both sides of the issue in a thoughtful (and mildly silly) way.

You could also check out YongYea, who covers video game trends and industry news, and has covered the issue.

As for the issue of early access, all I can give you is information that people have already echoed in this thread, that some gamers view early access games in a negative light, due to the perception that it is effectively a "soft release" of an unfinished product, or that the company is outsourcing pre-release testing to the public, and making them pay for it at the same time. I don't think it's a big discussion by actual game devs at the moment, only by regular idiots like me. I personally don't think BG3 was one of those games that treated early access like a soft release, even if i think they could have done things differently.
