The simple fact that you're defending this shows how desperate you are to increase your Larian Fanboy Cringeometer™.
"I'm an orphan raised in Candlekeep, my adoptive father has been assassinated" is a perfectly fine background that would be accepted in most sensible campaigns.
On the other hand, the clusterfuck that BG3 went for would be ridiculed by any player with even the smallest semblance of a functioning brain.
It's not Larian's fault, this is simply how things have to be presented to be accepted by the D&D 5 community. Why can't you accept it? Why do you have to pretend that this retarded pathetic excuse for a plot hook is even remotely similar to what BG1 did?
how many orphans do you think candlekeep has, on average?
why would candlekeep have an orphan there, one of the worst possible places to raise a child?
literally the only reason to keep a child there would be if he's either dangerous to others or others are dangerous to him
if you thought you were some random orphan at the start of the game, then you only have your ignorance to blame
This is just weird autistposting for the sake of winning some imaginary game.
Here's some facts instead:
1. BG1 has a classic simple low-level start. An orphan in a peaceful secluded location. Basic stuff.
2. BG3 starts with you escaping a crashing illithid space ship. That alone would be fine for an adventure focused on illithids. But the space ship is flying through ABYSS because... adding another wildly different high-level theme to the intro will make it more epic? Does Michael Bay work for Larian? And the tadpole in your brain is not a regular eldritch alien tadpole... it's super special and magical (add another high level theme later).
3. This whole thing can be made worse by playing a pre-made character. Why would you be just a boring CHARNAME with a magical tadpole flying through hell when you can also have a netheril nuke in your ass?
4. This is all the very beginning. Throwing all this cacophony in your face.
