I don't think they really dumbed down the D&D stuff especially, they just inexplicably changed stuff that didn't need changing...
like (and this a minor one) a firebolt in pnp? Simple 1d10 fire damage that improves at certainly levels getting an extra dice, in BG3? it does 1d6 fire damage, but also bonus fire damage that isn't explained, oh and it makes a surface which automatically causes burning with no save. That isn't simpler, its more complicated and actually detrimental as the amount of damage the spell now does is too high and far too dangerous for a cantrip.
There are many similar changes, rarely do they feel like they were simplifiying, if anything they're often overcomplicating or overcompensating for a previous overcomplication (at least from my perspective!)
