Not choosing or
actively avoiding to portray companies in a certain light is equally political as it is also a stance: The stance to be politically correct, or to be anti-socialist, conservative or what happens to fit in the particular case.
While I agree with you that political messages are most effective when they're not too obvious, which also goes for all kinds of propaganda really, I would to the contrary love to see more "political" games out there as they have plenty to tell and are a great way to escape the, from my perspective, generally totally braindead game industry that lacks a meaningful narrative due to it's fear to upset this or that group and it's intention to sell plenty and be easily consumed (often translates to bland generic stories a la Hollywood).
