I support these options when they are available. But when you have a certain taste for specific niche of games, sometimes there is no alternative. Kickstarter has managed to bring back the classic top down, turn based party RPGs, which is fantastic, but I haven't seen any developer try to bring genres like RPG sandbox (ala Skyrim) or grid based, turn based dungeon crawlers (MMXL, which has one of the most annoying DRM, is the first game to be released in the genre in decades) to Kickstarter yet.
Sure, I'm making a dent on my integrity by buying these games but I don't see it as a great evil as long as we're still able to fight against privacy-invading schemes. If that option was no longer there, I would stop playing these games. I also feel that the developers deserve the support, they aren't responsible for the publishers requirements. I don't wish for them to go out of business, I'm optimistic that the growing success of Kickstarter and gog as a platform might change their mind in the long term, I don't think it's all black & white where we either support kickstarter or support DRM published games.
I'll remind you that many of the current great kickstarter developers come from a classic DRM supporting background. Obsidian, for example. Their last RPG, Fallout New Vegas, depended on Steam as their DRM. They saw the success of kickstarter, started their own project on it (Pillars of Eternity), succeeded in crowdfunding it and might end up relying more often on crowdfunding their games in the future. Pillars of Eternity will be DRM-free.
Now the question is, do you think it would've been better if no one had bought their games before? You think it would have been better if they had gone out of business? I do not believe so. PoE exists today because Obsidian could afford to build itself as a studio and recruit some of the best developers of the genre.
Showing support for crowdfunding, buying games on gog.com will help these developers free themselves from the shackles of the bad publishers. Boycotting developers that are still kept in shackles will not do anything but destroy their livelihood. Particularly as publishers are very likely to blame piracy when the games don't sell well.
The fact that a lot of pre-established developers are turning to crowdfunding bodes well for the future in my mind.
