So I'm just dinking with Start8 right now; is it me or does it not implement hot corners correctly? If you actually go to the very bottom left corner of your screen, you can't bring the Start8 menu up. You have to actually be over the icon to use it, whereas the real start menu was far more forgiving since it treated that as a hot corner.
You might want to go into the settings for Start8, there is a switch in there to disable the new Win8 hot corners, and that might be what is causing your problem.
Regarding the guy railing against the evil capitalists that deign to charge for their work... Stardock is an established company that has been making software for Windows for years and years, and has you know, a staff. I don't know about all the free options out there, but I would imagine that a fair number of them are from 1-2 man shops (if they are shops at all) that just banged out the code and then put it on the web. I am not saying that Stardock's solution is better, but it is worth $5, and the fact that there are free alternatives speaks more about the devs of the alternatives than it does about Stardock. Charging for your work is not a crime, and the presence of free software does not degrade the qualities or status of paid software. I would rather see a wide variety of reasonably priced, good software, then deal with the status quo, which is 98% free crap, and 2% overpriced software.
