Least hated? I very much doubt that. I'd really want to see some evidence, because every poll on this sort of approach I've seen, over four editions (because it is an approach some people insist on), has been pretty negative on it (it's usually either most-unpopular, or second-most after some particularly bizarre approach).
It's a simple approach, but it's a bad one. I'm not against Psionic spells existing - but to make them how Psionics works is rubbish.
It's not a question of over 4 editions, it's only a question of what the customer base, as a generalization, likes right now. And right now, the majority of the customer base never even played a prior edition and do not appear to have any attachment to psionics as something other than spells They did do polls, they did get feedback, and this appears to be the least objectionable to this particular customer base for this edition.
And they don't need to show you their cards by the way. Their data is collected for them to make decisions. Their data wouldn't change your preferences anyway, so what would be the purpose of "providing you evidence"?
