Fuck Tasha’s.
All my homies hate Tasha’s.
That's basically my stance. I consider Tasha's the worst supplement to 5E and will quit any group that uses it.
Out of the 12 people in the D&D groups I play in, only 1 guy genuinely likes Tasha's and 1 guy likes parts of it. The rest either outright hates it or is indifferent.
As for BG3 being OneD&D ... I think the assumption holds some truth at least. I'm not entirely sure how their licensing system works now, after their proposed changes caused some rather huge backlash.
It is a fairly safe bet that OneD&D had at least some influence on the changes to BG3 post patch 9.
