Get a license to have their stuff on a console where piracy isn't an issue.
Since when is this not an issue? Enabling backups on the Wii is almost trivial, these days. And modchip installation is only getting easier.
...now its having to be online just to play a single player campaign.
Don't forget requiring gamers to buy each campaign separately.
Are you willing to give up video gaming altogether once all the major publishers of PC games have switched to this business model?
I'd be much more willing to get into reverse engineering, actually.

You must not have a Wii, because it's quite a bit more complicated than that. For the sake of the community, allow me to explain:
There are ways to run homebrew on a Wii without leaving (much) trace. The problem is that this is really inconvenient to do, so most users opt to install the Homebrew Channel. This is where Nintendo believes their justification comes in. The install method includes using a hacked save file for Twilight Princess. The horse's name in the game has been changed to induce a stack smash, enabling some shell code to run that launches the Homebrew Channel installer.
This of course poses certain risks, but to date I don't think anyone has had any problems since Nintendo has been taking measures to prevent the Homebrew Channel from being installed. So basically, it either works fine, or not at all. I have yet to see the HBC pose any real risk or hear of it causing problems.
And that's just scratching the surface. There are custom IOS modifications that can allow you to run backups, play actual DVDs, change your system menu themes, and a plethora of other things that could potentially cause problems if not used with caution.
Preloader (I mentioned it in an above comment) works by renaming the system menu and installing itself in its place. When SM4.0 was released, there were some problems that would cause your Wii to report that it was bricked. This has since been fixed, and I don't think the Wii homebrew communtiy worried about it too much because the problem was a known issue and has since been fixed.
And don't get me started on pirate WAD installations that let you install virtual console and WiiWare titles for free. What I'm getting at is that it's painfully obvious when a Wii has been modified. The current IOS is v60, and a lot of IOS mods install to IOS v249 or 247. One look at your Wii's NAND will tell the tale.
