Apple dropped Intel because Intel lost too much ground (2022 before Intel gets to where AMD is with manufacturing) switching to lower nm production (lower nm means faster CPUs using less power) and their own ARM CPUs were proving to be pretty good in iPads (faster than Intel X86). Overall, it just made sense to Apple to completely move over to their own ARM CPUs.
MacOS for X86 can be gotten to run on non-Apple X86 hardware only time will tell if it's the same for MacOS/ARM. It makes sense to Hackintosh because Apple laptops and computers are overpriced, still remain overpriced on the second-hand market compared with like-for-like hardware.
Apple's deal with their hardware is not so much to tie their OS to it but to prevent repair by 3rd parties.
This is visible with components in iPhones being coded to the phone (3rd parties cannot replace buttons) and T2. Instead of a simple repair, it forces customers to take their Apple phones or computers to the Apple store or approved repair centre where they often get convinced through upselling (repairs are so often prohibitively expensive compared to buying new) to replace the phone or computer.
