As much as I like knowing about companies that I buy from, if I'm on a product page, looking at a product review, I'm expecting the product review, not the moral compass of the company. If I wanted to see the controversies the company is involved in, I would search the company online.
If the controversy involves the game sure, but if the only association to the game is that the publisher or dev made it, then I really don't want it in the reviews, that's not what I'm looking for.
Examples of what should be in a product review:
- Developer controversies that effect gameplay (like the Ark Survival controversy that shut down servers and failed to deliver on promises)
- Gameplay complaints/reviews
- Potential software or regional restrictions such as DRM or region locks(steam disagrees with this sadly cause they'll mark it offtopic)
- If the developer is a scam artist/illegitimate
Examples of what shouldn't be in a product review:
- Backlash from a social media posting
- Politics
- Ideologies
- Memes/Jokes (imo these are fine if its gameplay related like the skyrim arrow to the knee reviews, but usually they aren't)
