Perhaps Android should have a "simple" mode and a normal mode, that could soften the problem.
Simple mode gives the default settings and they are unchangeble (lock screen, default mail app, default browser) and kinda whitelists apps on their features (no replacement apps) and a normal mode for everyone else who is willing to use Tasker and other apps.
PS. The author of the referenced article kinda forgot Tasker :s
To bad for him though.
