Are you talking about Ladybird?
The US government is a mess but US companies still have all the money. Most Canadian companies have US revenues and will benefit from US deductions.
The first big Ladybird sponsor was Shopify. They are a Canadian company that recently moved their headquarters to the US.
Agree with your last sentence.

What year?
I have several Mac laptops running Linux with hardware from 2012 to 2020. I find that EndeavourOS works best and WiFi works out of the box.
It uses the wl drivers generally (NOT b43) with DKMS so the module is automatically rebuilt when you upgrade the kernel. You can just upgrade the kernel using the package manager and it “just works” when you reboot. I have been using Linux on MacBook Pro and MacBook Air systems for years and never had a problem (2012, 2013, 2017, 2020). Also iMacs back to 2008.
If you have a T2 chip system, you need a special kernel and apple an wifi/bluetooth firmware blob. In most distros you have to extract the firmware from macOS yourself but it is available in the AUR so there is a special T2 addition of EndeavourOS that makes everything work out of the box. These are the 2019 or 2020 systems I think.
