I consider using patents to extract payment a far lesser evil than lobbying for them. And an even lesser evil if the patent has some merit to it, and is licensed openly (i.e. no confidentiality terms to prevent revealing which parts of Android they claim to have patented).
As for your question - Cloudfront springs to mind - they're pretty loud about going after patent trolls, which implies they might not use patents aggressively. I'm sure there are many others, but a company not using patents to extract payment isn't something you hear about, so it's hard to tell. That said, despite filing for many patents, I haven't heard of Facebook actually using them against others. Which isn't to say they haven't done so (and possibly, like MS, kept the agreement confidential), and of course Facebook is hardly ethical itself.
Another poster says Microsoft joined the Open Invention Network, so perhaps in that area, they've reformed. Though they could still be lobbying for patents, which does much more damage to user freedom.
