Page 23 of the ISU Technical Handbook states: "A clear forward (backward for Axel type jump) take-off will be considered as a downgraded jump. The toe loop is the most commonly cheated on take-off jump. The TP may only watch the replay in regular speed to determine the cheat and downgrade on the take off (more often in combinations or sequences)."
So, don't take my word for it that forward takeoffs are incorrect (except for axels); the ISU has decreed it.
And, no, loops and salchows don't need a straight takeoff. They need a slightly curved takeoff. Jumps are done from edges. They are not done from flats.
Sorry but you have no idea what you're talking about (the ISU handbook doesn't really either, about all of these specifics).
Being in line for a takeoff on an edge jump has nothing to do with flats, and "edge jumps" should all hit the toepick at the end of the takeoff, they don't actually leave the ice solely from the edge itself. For the Loop and Salchow you want a half turn on the ice as you takeoff. Doing less (at least for a Triple or higher) is just going to make you prone to harmful misalignment of the hip. That's why someone like Kurt Browning was so much less consistent and more prone to injury back then, these techniques hadn't yet been refined.
For the axel you want at least 1/4 turn prerotation and up to 1/2 is fine too, hitting the toepick at the end of the takeoff. Again, people also tried to do "clean edge" axels in the past and it resulted in jumps that more frequently will throw you off your center (although they can look great when done right, like Jeremy Abbott's 3Axels he used to do with that technique).
The rulebook is just stating that a turn to forwards on the skating foot (not toepick foot) of toepick jumps is invalid, and for edge jumps you need to stay on the correct edge, rather than turning the opposite direction to a different edge and then jumping.

Here is how I rank the skaters based on PreRotation from most to least.
Zhenia....just under halfway.
Anna...just about halfway.
Ashley...over halfway
Satoko....over 270
Thoughts?
Evengenia is 270 degrees pre-rotation or very nearly, look at where the first jump lands, the back of the skate pointing at the side board, and then by the time she leaves the ice the toepick is facing the board at the other end of the rink.
Satako is 270 degrees pre-rotation (sometimes she does even a bit more); on that jump in particular you didn't have a good angle and froze the image too late when she was already in the air. She doesn't land completely backwards, though, which you need to be doing when you are pre-rotating 270 degrees. That's why the jump should have been called as underrotated.
Ashley is 180 degrees or just ever so slightly past that amount, usually she is 270 degrees (or nearly), so this made me very happy to see from her last week.
Anna is 180 degrees.
How's this:

No rotation done on the toe pick on the ice. At all.
Yu-Na pre-rotates her toeloop more than 1/4 of a turn. Pretty much everyone does (and everyone pre-rotates 1/4 at the very least). Dasikuke Takahashi would sometimes only pre-rotate 1/4 turn on his toeloop (and pretty much always less than 1/2) and it would get him into trouble with tech panels because they wouldn't pay attention to how he was starting the rotation earlier; they would just dock him on the landing point.
