They sell Macs with macOS. That's what you pay for and that's the deal. You know that jumping in. You want to run another OS, that's on you, Apple owes you nothing.
If you think that laptops deserve to become e-waste when the OEM says so, then your opinion can be safely discarded.
So can yours? It's only opinions, my guy. I still have my 2015 MPB Retina. The battery is busted, one speaker gave out. Still works though. Runs Proxmox. But, it's 11 years old and it's done its fair share of tours of duty. I got my $ worth.
