I totally think that when a Vox Media publication writes about Comcast that they should disclose the fact that Comcast Ventures owns a minority stake in Vox Media. However, I think it's a bit ridiculous to expect them to disclose this every time they cover one of their investor's portfolio companies. According to Crunchbase [1], there are 1,124 companies that share at least one investor with Vox Media. That's a pretty large list for editors to keep track of. I'm not aware of any publication that provide disclosure statements when they cover one of their investor's portfolio companies.
