I have two problems with high speed.
The first is as Joshua said - it makes the game harder to follow for people who aren't as adept. It's hard to appreciate good decision-making by the players if you can't mentally keep up with the speed the game is going. It also doesn't help if the game progresses too quickly for the commentators to recognise and explain good decision-making. If you can't process Tetris quickly enough to keep up with what is actually being done with the pieces, then for the spectator you might as well not see the pieces at all and just show the stack because that's about all they can really process. Sure, you get the impressive factor with high speed, but that doesn't actually hold any long-term value for anyone.
The second is that it makes games end too quickly. And I don't mean in terms of having 10 second matches - I mean in terms of a player going from "OK" to "dead" in far too short a space of time. A lot of excitement in sports and eSports hinges around tension and not knowing what is about to happen next. If a player is about to top out, then the longer they sit on the brink of death, the more tension is raised as to whether they'll be able to survive it or not. When you combine 180tpm with the ability to easily send 6-10 lines in an incredibly short space of time, you totally eliminate any chance for that sort of excitement to build unless you're extremely good at following the game.
Speed is an easy way to increase the skill ceiling, but I think it's a fairly cheap and blunt way to do so, and it makes the game less interesting as a result.

even chess is not olympic.
Its federation is recognised by the IOC though (http://en.wikipedia.org/wiki/Olympic_sports)
And eSports won't ever be in the Olympics for the same reason that darts, chess, pool, etc won't ever be in the Olympics, which is that they don't represent feats of physical technique, strength or athleticism and they're not what the Olympic games are actually meant to be about. Regardless of anything else about the success of something as an eSport, it's just silly media chatter to suggest anything like that will be included in the Olympics unless there's a massive overhaul of the system.
And if one does somehow make it in, then it'll be the equivalent of SC2/LoL/whatever is popular at the time that makes it.
