It may be just a coincidence but I have started noticing that very often when a company has a post that criticizes it for some behavior trending another post immediately follows showing the "generosity" of the same company showcasing some OSS or a blog post about some popular technological subject.

It got me thinking that maybe those companies have bots ready to upvote nice things about them when some criticism surfaces.

I've seen this happen with both Google and Microsoft so far.
