I think, for starters, it depends on how you define netdecking. Some may say netdecking is when someone copies a deck exactly as it is posted (on Top 32 listings, etc.), and uses it without changing it. I describe netdecking as using the same general strategy and that you could say a huge percentage of players netdeck. After all, if a deck works, why screw with it? Some people just aren't hugely talented at deck building.
Next, your intention factors in. Some use netdecking as a learning tool, how to better adapt the deck to their own play style, etc. Sadly, however, some also think they can just jump into the game by buying the cards listed in a YCS winning deck (or another successful deck) and achieve greatness. In respect to the above, I think netdecking is ultimately something that CAN be used for good, but may often be used for evil as well. However, that being said, I don't know if I can really say whether or not netdecking itself is an inherent good, since in this case, it's rather subjective.
Whether you love netdecking or hate it is also ultimately up to your philosophy. Do you play all-out with the intent to win, or do you play for the enjoyment of the game? Those on the latter end of the spectrum may find netdecking more annoying, while those on the all-out side may find it to be an essential tool. Competitive players typically find more value in going by the book (or in this case, what is working out for others) and culling personal techs to a minimum, since those personal choices may not always win you games, whilst Casual players may find their enjoyment coming from playing a lot of those personal card choices. I don't think anyone is right or wrong in that respect, it's just how they think the game should be played.
An ideal tournament will get a healthy percentage of both kinds of players, casual and competitive. Local tournaments will probably have higher percentages of casual players, whereas Regional tournaments and the like will probably end up with higher percentages of super-competitive players due to the associated status of these bigger tournaments (the ratio of those competitive players to casual players growing ever less proportional, based on the prestige of the tournament, if you play in the West). It's unfortunate to end up with a whole bunch of those ultra-competitive players who enjoy tearing at each others' throats every time they lose because of all that money they spent on a tourney-winning deck, but such is the nature of such a competition-centric game, and the human beings behind it in general.
