Red_Avatar: I strongly dislike Valve and Steam as a company but I don't boycott them in the sense that I don't use the service. I do, however, refuse to buy them at full price (heck, 50% off is the minimum) and, if possible, buy the games elsewhere. For example, I buy a lot of CD keys from shops at a third or a quarter of retail price if they're Steam exclusives (like Sleeping Dogs and Borderlands 2). If publishers insist on using Steam, that's what they get.
That pretty much sums up my stance as well.
Having to create a new Steam and email account for every new game tied to this, plus the same procedure again if I have to contact their support, regional restrictions that force me to use a VPN, mandatory updates and cloud syncing (both of which is great if it's optional)...
All those inconveniences greatly devalue anything that requires me to put up with them, so paying the full RRP for a Steam game is out of the question.
A personal anecdote, I did boycott Steam for a few years, starting shortly after it was made public. Initially I was thrilled to give it a try, being an avid player of Half-Life mods and a bit of a Valve fan. The plethora of issues quickly turned me away, and Valve forcefully converting the multiplayer community by shutting down WON in order to establish Steam was certainly a smart business move, but destroyed most of my goodwill. The rest of it went away after I played Half-Life 2 several years later.
