On re-reading the sidebar, I actually find that you are wrong. The text clearly states that the Twisted's abilities are "probably beyond the scope" of a normal table, but then goes on to say (almost to encourage) its exploration anyways. Then there is a disclaimer for inexperienced GMs, and lastly states that metamagics should be very rare to preserve game balance. Nowhere does it actually state that those abilities are not intended for PCs, just that allowing those for PCs could shift "game balance," which is a remarkably subjective theory (for example, what I would find par for the course TJ would find game-changingly bad).
You should re-read it again...
A couple of relevant quoutes...

While many shadowrunners might qualify as borderline sociopaths and psychotics, roleplaying a truly demented individual with Awakened power at his fingertips is beyond the scope of the Shadowrun rules and the team nature of a typical game.
For example, blood magic is a ruthless practice that involves the cold-blooded murder of a living creature for fleeting empowerment. It is the kind of heinous act only a completely callous, unscrupulous, or highly-disturbed individual might commit. Despite some runner’s reputations, such activities are not conducive to a long career and acceptance in the shadows.
Additionally, the twisted gain access to obscure arts and unique metamagic techniques that can be potentially unbalancing in a player’s hands; gamemasters should consider carefully before allowing them into the game.
See, intrinsincly, they are not for Player Characters. IF you allow such themes into your game, you are well beyond the scope of the rules provided by the Setting. Says so right on the box, first sentence in fact. And if you read the entire sidebar, nowhere does it encourage such playstyles. It simply points out that they are not the norm, and that such themes are generally uncomfortable for most. Obviously,
Neraph, you are not bothered by such themes. However, many other people are.
