Google, on the other hand, has no history whatsoever of using patents offensively. I don't think [1] they've made a single offensive patent case, ever. If the morality of a company is going to affect your choice, Google is by far the better choice.
[1]: I haven't verified this statement. It probably doesn't hold true for some of the companies that they have purchased, e.g. Motorola Mobility.
And yeah, your footnote definitely doesn't hold true for a number of the companies Google purchased, which I don't (directly) hold against Google.
I think I remember one of Google's top IP lawyers has even said that software patents probably shouldn't exist.
Claiming that a company must not protect itself from frivolous litigation in favor of working to dismantle the patent system is like claiming that an AIDS doctor shouldn't be allowed to use protection during sex and should instead focus on curing AIDS. You can do both at the same time.
Apparently it is, and this is pointless. I get it, hate Apple, love Google, we're warming back up to Microsoft and uncomfortable with Facebook.
We do not know that Google uses their patents offensively. At least, not that I am aware of. This doesn't necessarily mean that they won't or that they haven't. But it would be wrong to ignore past action as a predictor for future behavior.
