thaey cant stop it from happening, what they gonna do, visit everyones house to make sure they not sitting there soldering in a chip.
They will attempt future updates to block out the chips, this will fail as there is no need to update anyway. If you just wanna play backups then you can leave your Wii on 2.1, 2.2, 3.0 and update no further. Don't use Wiiconnect24 and your Wii won't auto update.
Games which have updates on them can have the updates disabled anyway from the iso before burning to disc.
Give it a couple more months and new chips will be out to bypass this anyway.
Hackers are always 1 step ahead of the companies anyway all the time.
