Valve Blocks Competitor from putting APP on steam

Well, thread has run its course and is now closed. Apparently it was deemed as an april fools joke - if an expensive one. Given the account used to upload the "Itch.io desktop application" only has that on greenlight. More worrisome is the fact the news blog Kotaku posted an article as factual information.

I did learn a few things from this however, notably more about how itch.io operates. Though not where the hell I came up with them using a ".to" domain in initial writings. Whitelisted one guy, and blacklisted another too, but that's another story.

Just came across an interesting article posted yesterday. Couldn't find a thread on search, and thought might be something of interest to some. Essentially, Itch.io put an app on steam greenlight. That App has since been removed for a half arsed reason, taken to be because of "competition".

Said reason was because the application didn't fit into what they considered to be "valid categories of software", even though they go out of their way to state "recent changes" implying those changes could have been made purely as a way for them to be able to give a "real" reason for the removal.

Looking at this as a business perspective, I don't see the problem with this. Valve, from what I've read many times, take a minimum 30% cut from any sales, so it would just be yet another opportunity to gather a bit of income for them, plus the itch.to team would essentially be advertising for steam, directing people to the app, where they might find other sales in the process.

That is, of course, if it was being sold at all. It would appear to have been This Application available on their site, allowing users to access their itch.to games on the desktop, much like steam actually is.

Which would further spark consideration that it was disallowed purely for hosting a competitor's application, likely also because, if I'm not mistaken, Itch.to hosts indie developers games at no cost, versus the $100 price tag to become a "greenlight developer" on Steam, plus cut of the sales?

Does itch.to take any of the profits, or charge anything for indie developers on their platform?

What are your thoughts? Was the removal of the application a genuine one, or had Valve found some excuse to remove it being a competitor platform for game distribution?
Would figure if Valve can make excuses to remove applications like this one that they'd get rid of some of the garbage on Greenlight, and "clearing" past Greenlight... There's plenty of topics already on this sort of subject. Some games, and even entire developers, shouldn't even exist on steam in the first place.
