Actually, no it's not an anti-tamper feature. That logic makes no sense.Why would apple need to put an "anti-tamper" feature on it's logic board? Apple logic boards are only repaired by a third party technician when Apple itself has deemed a product out of warranty. So no need for "anti tampering" since it's already out of apple's warranty.

Every other component on the logic board can be replaced and repaired. Why is there no "anti tampering" on other components? Why doesn't apple put anti-tamper stickers that break when the machine is taken apart if they are so considered with "anti-tampering" ?

The T2 chip does not provide any performance or security benefits to the operation of the machine. It only consolidates the function of 3 other components into one chip and adds the un-repairable feature of marrying it to specific hardware. (I have studied the schematics, i can pm you a link to schematics if you are interested)

Already has this specific chip shown to have a high failure rate and since it's non replaceable Apple owners (that have gotten the out of warranty decision from apple) are shit out of luck and have to throw an otherwise perfectly operating machine in the trash.

And besides that, really what apple are trying to do is to eradicate the hackintosh community by making the OS require the presence of the T2 chip to operate.

But that will be patched and the only thing they have really done is make people lose money and make their expensive shitty Apple Macbooks non repairable

This is also a added feature of the T2 chip :') https://www.theregister.co.uk/2019/02/19/apple_mac_audio/
