I don't follow these technique threads too carefully, but sometimes find some amusement in them. It seems to me that so much of the debate is a result of differing definitions of 'technique.' I for one include all of the physical aspects of piano playing in my definition of technique- speed and accuracy are encompassed in it of course, but so too are many, many other things. If everyone else in the world agreed that piano technique should really only be in reference to speed and accuracy, would that change anything for me? I would just say that my definition of good piano playing included all of the physical aspects, which encompasses 'technique' but also many, many other things.....
For me, the particular words used are immaterial, but I would be interested to know if others find more importance in the specific terms. Is there an advantage or disadvantage to technique meaning more than just speed and accuracy?
