Some absolutely do, some nominally don’t but don’t stop to think about the implications of what they say they want, and probably most think education is great. The term Christian refers to so many people that making any broad assertions is going to be wrong for large percentages of the group.
Apple does its best to block everyone else from collecting data on users. They want a monopoly on that stuff.
Turning code usable by machines into anything remotely readable is really hard. Hard enough that the people doing it are either doing it as a hobby, meaning the output quality isn’t a concern, or there has to be massive amounts of potential profit. For something like iOS the second isn’t ever going to be the case because competitors outright can’t really use the source code if they did get it, that’s protected by copyright or something. On the hobby side however, code decompilation is a thing that happens from time to time.
TLDR: the difficulty is in making the source code readable, not in getting the source code.
To be fair, people stopped after starting a witch hunt for the Boston bombers and identifying the completely wrong people. It may very well be the case that they over corrected, but there is at least a good reason for the change overall. (also corporate interests I suppose, fuck them though)
