Everything in that article is nothing but common sense if you have ever bought a new car before.Then Ford is contradicting themselves.

It's not a secret modifying your car can void the warranty on that specific part. It's not a secret that if said modification causes the issue, you're out of warranty. It's not a secret that power mods can lead to premature wear.
Nothing in your link is Ford contradicting themselves if you read the key words, "shade tree mechanic". There's 2 parts to that; 1 being that Ford & well known tuners obviously aren't "shade tree mechanics", so the parts they offer are designed to offer more performance without any serious risk. The 2nd part is the owner having an understanding of the engine's limits & knowing that the installation of certain mods will need other mods to support the aforementioned mod. If the block is maxed out, obviously trying to run certain modifications will be risky. If a supporting mod is installed, however, the block's limits are expanded.
What you also posted is a TSB that every single manufacturer sends out on new cars. My BMW has one as does my Acura as does the new GS, LS, & IS booklets we have been trained on through my work.
