No. Companies need to remain neutral as much as possible. After all, there are two sides to pretty much any debate and there's no reason a company needs to start taking opinionated sides on things that are totally unrelated to their business.

that is mostly my stand, but also companies are a group of people coming together for a cause - which they think is important - serving others.
For example maybe we should tell people more about the importance of open source or privacy?
