And hey, you are welcome to prove me wrong. Show me the "signs of mismanagement" I just indicated. 300+ employees - somebody should be saying something.
I wanted to avoid bringing this up on THIS forum, but since you're asking...
That said, typically we don't really hear anything major in regards to mismanagement until much later. If BG3 truly is being as mismanaged as some here fear, I don't think we would realistically hear anything about it until after the game is released, when people have a chance to distance themselves from the project and company (and will be in less of a position to have their salaries/livelihood threatened via any retaliation). Not to mention Larian is now the current media darling, now that literally every other major western RPG developer has fallen flat on their faces in recent time. The same way CDPR used to be the media darling up until Cyberpunk shattered their carefully crafted façade. Point being, anything remotely negative won't be taken seriously, until things become so obviously bad that public opinion shifts enough to a level where articles about this alleged mismanagement can be safely written.
We only really hear of mismanagement before release if the project has reached truly unsalvageable levels, like CDPR with Cyberpunk. I think another big example is Bioware due to how absolutely consistent the reports of mismanagement were over the entire past decade, but upon further thought, that information only began coming out after the release of each of their projects. DA4 is an exception, having known to have restarted development once or twice, but we only really know that because people are now heavily scrutinizing the company for any information about the project (plus the failure of Andromeda and Anthem affecting DA4's development) to begin with.
