Whose choice? The kids? Because we all know kids aren’t easily tricked. By their parents? If Anikin’s mom is any indicator, she was effectively lied to and filled with unverifiable promises by a stranger she just met who certainly wasn’t using their current situation as a means to appeal to her emotions about her wanting a better life for her son.

Isn't the new show just canon saying they forced them/the jedi had to bring them in bcs of the threat they would become sith?

Also nobody went & rescue Vaders parents, they just bought a child slave (if he would work for them that is), and neither the planetary royalty nor the galactic Jedi order didn't have the funds to buy two parent slaves (or help the planet for that matter).

Not really. And this isn't something "Disney canon" either, as this was established well before Disney, when Lucas still had creative control:

The Jedi, in their archives, keep a list of force-sensitive children. The extra-powerful ones, ones that can already manipulate the force at an infant stage, are kept on a well guarded holochron in the deepest part of their archives.

Jedi observe these infants. They visit the family's of these infants. The parents are told there will be a day that they'll come for their kids. Then, when they're old enough (but not too old) the kids get taken away from their parents and start training at the nearest temple (or the main one).

I haven't heard of Jedi forcibly taking children away, but Jedi can be very... convincing, so "on paper" these kids are there by choice. These stories were explored in The Clone Wars. One of the earlier seasons. Though it didn't go into specifics.

Those 3-4 year olds making those heavy decisions...

A child cannot consent to be taken away from their family like that.

Its abduction, the Jedi suck shit and abduct child to be children soldiers and enslave sentient robots.
