You are here on behalf of not just publishers, newspapers and magazines, but also community organizations. I see the two as completely separate.
There is a difference between investing in a business and investing in a community organization. To my knowledge, the government has always placed ads in all sorts of newspapers, community-based and private alike. Correct me if I'm wrong, but you are asking the government to subsidize community media and organizations in francophone minority communities. I see no problem with that.
