Who is trying to control anything? Wine developers have explained PE vs elf in the past (I think even in some past release notes). This is like trying to accuse a math paper of gatekeeping because it uses notation you don't understand.
Jargon is a thing.
Here's a link to a news article discussing how jargon can be a gatekeeper of knowledge [0].
To be honest, that wasn't even my point but that a specific counter example to your claim being available is hilarious.

At some point, people have to assume a certain level of knowledge. And as you implied with your article, there's nothing stops someone from Googling jargon for more context. Others have pointed this out, but the Wine devs have talked extensively in other materials about these concepts. This is a REALLY good article about how Wine works with kernel modules end-to-end: https://wiki.winehq.org/Wine_Developer%27s_Guide/Kernel_modu...
And if THAT doesn't make sense, keep adding to the stack with more web searches and videos.
I just don't know how else someone would expect to get into a topic like this. Plus, these are _release notes_, not learning materials.
