So we are excusing this just because is Larian? Interesting... Specially with all those Outrage Videos about Blizzard, EA, etc... and how this was the Second Coming of Christ of Releases in the Videogaming Industry while Larian just swept this under the Rug. Of course anyone would want the Game to be finished but i don't know how to feel about them now...
Sure. It's called goodwill. I don't believe Larian has intentionally missrepresented or misadvertised the game. Something went wrong, at some point. Larian has also trackrecord of continued free support for their games. Frankly, the game is in much better state than I anticipated, and as someone who has been playing the game since early EA, that the game still isn't finished, isn't really that much of a dealbreaker for me.
What soured, at least me, on the other companies you mentioned is their business practices. In that regard Larian is as good as it gets - single purchase, reasonably priced game, aimed to be fun, not to nickel and dime players.
I am not as enthusiastic about BG3 as some other individuals, but I am find no fault with the game as a product.
