This thread is boring, so lets do that.
Youtube and the subsequent proliferation of combo/match videos has greatly decreased the variance the community had from regional playstyles. Instead of mostly developing their own way of playing with minimal input, new players were able to emulate other styles and tactics they saw online. It has killed whatever creative ways of playing they may have developed, replacing them with repeated, almost-scripted playstyles. This largely homogenizing effect on the community can still be felt, as flashier, easier to master tech-skill became the focus of many players (tech skill inadvertently becoming synonymous with ability for many people), leaving emphasis on smarter playstyles by the wayside for newer players.
Low tech skill almost doesn't exist anymore, simply because it is so very easy to do most of the tech skill related stuff in the game and it opens up a lot of possibilities. Some characters like jigglypuff and falcon don't necessarily need a lot of tech skill to be effective, yet those players are all still very competent at technical things.
Any player with a propensity towards a smart, non-technical playstyle that may not require a large amount of tech skill has still obtained that tech skill anyway. This is because there's no reason not to be technically proficient in addition to playing intelligently, especially since tech skill is obtained through rote practice.
