I can't say that I'm totally happy with Steam, but it's a lot better now than it was a year ago. They've added a handful of QOL features that make browsing through things a lot less bothersome than it was before. In-home streaming is also great.
I had over 700 trading cards collecting dust in my inventory that I could have either sold for Steam credit, traded for other cards or used them to bid on some games as a nice little meta game. I had a handful of games on my list that I was interested in, but didn't want to plunk down any of my own money on (short of steep discounts), so I turned my cards into gems and got 6 games for little more than my time spent converting cards and watching auctions. There was the option to spend money on it, but I never saw the point. If I won some free games, great, if not, I could sell the gems or make booster packs. At no point was I put on the losing end of things. I'm sure Valve made bank off the gems, but that's more to do with people not spending their money wisely (or just having more than they know what to do with).
While I don't particularly like trading cards, in-game cosmetics, or even prettying up profile pages, some people do and are willing to spend money on such things. At no point am I ever felt "forced" to participate in any of it when it comes to Valve, though. I can just play the games that I have or jump into one of their free-to-play games and just have fun, if I unlock a trading card, I don't even have to look at the thing if I don't feel so inclined.
If you really feel like you're being "held hostage" by any of these systems, you need to take a step back and analyze what exactly you're getting out of any of it and if it's worth it to spend any money or even time on any of it. As far as Steam being offline, I haven't experienced any outage during this sale (granted I haven't been playing any multiplayer games on Steam) which is really strange for me so if nothing else, it's more stable for me than it was during the summer sale. Perhaps it's the server I'm connecting to, but I got one "Steam is very busy right now, try again in a few moments." message at the very start of the sale and haven't had a single hiccup since.
I don't think that make bad games, not by a long stretch, but they are revered in some peoples eyes. I understand I'm in the minority and different stroke and all that but their games just seem so average to me.
I can't think of anything that they've done that was "average" at the time it was released. As games have evolved, they may not seem as groundbreaking as they were, but in 1998 we were still stuck with Quake clones and pretty much only Quake clones when it came to FPS games. Valve added narrative and some, for the time, stunning A.I. and made a shooter that required a bit of forethought to conquer rather than just running in guns blazing all the time. It's considered a masterpiece because it, along with games like Rainbow Six, changed the status quo. And while Half-Life 2 may not have been quite as groundbreaking, it was still a huge achievement in 2004. To call anything that they've done "average" for the time it was released is paying Valve a huge disservice.
