Gaming interrupted by advertisement

Not all companies do, even gaming companies. Riot is a great example of that.

Do excuse me while I remove the bullpomegranate you just threw at my face.

Riot Games has continually tried to expand its player base and move into new territories since League of Legend's release.
It doesn't do these things out of the kindness of its heart; it's doing it to make more money.

Really the only alternatives I see now, are either to step back on purchasing games; or to support the developers directly. True games need cash in order to cover the bottom line; but if a developer is willing to drop the middle-man who financially backs him(ie publishers) in favor of holding all the risks themselves to gain back their virtues; we should support them.

That's fine and dandy for low-budget titles, but it's not a financially viable method of distribution for most titles.
That's equivalent to asking Joe Public to personally fund summer movies.

Why I am so pissed at these shady strategies is because I perceive games as a form of art. And when you try to make a business out of something intended for creative purpose; it skews a number of things. Ultimately, yes, it is a business; but they don't have to make it so damn clear to both the investors and the consumers.

Fixed that for you. Please don't try to pluralize your opinion in order to validate it.
I'm a gamer, and I don't see games as being art by their very nature.

There are games that are truly works of art, but that's hardly the norm.
To state that video games were created "for creative purposes" is an outright lie, in fact.
Arcade video games were an extension of mechanical arcade games. In both cases, they were created specifically to get those coins out of the players' pockets.

If you want to remain ignorant of how the world works, then that's your choice, but it's very disturbing that you'd rather have everyone be in the dark.
It's also kind of sadlarious that you think "investors" wouldn't be very clear that what they're investing in exists to make money.
