Most of the large tech companies mostly turn me off, though there are little glimmers of things they do that are positive. Ironically, I've been breaking my radio silence on G+ over the past couple of days discussing some of this in relation to Gundotra's exodus and the "death of G+" discussions (short answer: yes and no).
I just got accused of having favorable views of Facebook (I don't -- I think what the company does is detestable and Zuck's morals are beyond reprehensible .... except that the company's stand in breaking the wage-suppression collusion cabal was a stunning case of doing the right thing).
But in terms of a company which could tempt me ... there aren't many.
