That being said the people that maintain the filter lists I believe, don't quoute me on this, you can donate to a few of them. Really depends if they mention it on their githubs though and you pretty much have to go about finding them on your own as there's no real centralized list of all the people that contribue to the filter lists.
The funny thing about apple is just how far they've moved away from Jobs' "vision".
It was clearly evident when they released the Apple Pencil. Jobs hated Stylus'. one of the reasons he killed the newton, and a reason why the iphone/ipad never originally had one as he was quoted as saying "why would I need a stylus? I have 5 of them on my hand"
I mean Apple is like a cult that worship a dead god who would burn current Apple to the ground and start over if he came back.
