Not that weird as i understand it. DOS2 was early access and look how that turned out, it seems they want to repeat the same method that brought success.Larian Studios going EA again is a bit weird, though. They don't really need the money with the success of DOS 1 and 2, so they probably want community feedback then? I guess that's a positive thing and I do trust them. Getting BG3 sooner as a playable demo (let's call it that) is a good development. In any case, I wouldn't use Larian Studios as a bad example for EA.
In the end of the day, EA is as good as the developers use it. It can be either a genuine attempt to get feedback for a developing game and some investment or a cynical attempt to gain as much money as possible for a bad product. It is another of a long list of tricks consumers like us need to be suspicious of. Dont we have a great hobby?
