Looking awful has not prevented local dimming from becoming quite common on laptops. Apple has been doing an okay job of it in the MacBook Pro for several years. Lots of Windows laptops have been very hit-or-miss about it, but at least with those you often have an OLED option. I've seen multiple Windows laptops from more than one OEM where opening a terminal window with light text on a dark background means you can easily spot a single line of text getting much dimmer toward the center of the dark window, and lighter near the perimeter where it's close to other light content. And that's for static content; as you mentioned motion can bring more problems as the backlight lags behind the LCD.
Back in 2002 I took the HDD from one PC, put it in a different PC, worked just fine. The worst thing that could happen is that the other one already had another disk so I had to change /etc/fstab to say "hdb" instead of "hda" and vice versa. Didn't take long for that to get fixed by specifying UUIDs and having initramfs sort it out.
IDK why it's not working for you but this should all just work without bothering with any configuration, drivers, or whatever.
How is buying a midrange phone new a scam? Just because a second hand premium one is better value (assuming you don't place any value on being brand new). You buy it knowing full well that it isn't a premium device but most people don't need a premium device.
I expect a lot of people who run adblockers on mobile, also configure their DNS or use a VPN to block ads. On Android, you can't even get an adblocker on Chrome, which is the browser most users and using.
I recently did an install of Windows 11 on a machine without TPM
To bypass the check during installation:
Boot the laptop from your USB.
When you see the "This PC can't run Windows 11" screen, press Shift + F10 to open a command prompt.
Type regedit and hit Enter.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\Setup.
Right-click Setup, create a new Key named LabConfig.
Inside LabConfig, create two DWORD (32-bit) values:
BypassTPMCheck = 1
BypassSecureBootCheck = 1
Close the registry and the command prompt; the installer will now let you proceed.
It's a never-ending cat-and-mouse game, and unsupported hacks like these usually aren't well-received in corporate environments. Decent stop-gap for home use, though!
You can sell the old Macbook and recoup a lot of the original investment.
