It’s funny because it’s true. Often one needs to check the dedicated sub and a more general one to get unbiased takes/reviews, e.g. ubiquiti and networking
Whether by social group principals (grassroots), or self interest promotion (corporate), this is the thing that has been infecting the Reddit platform for years making it less fun to use.
* participating in the subs in good faith, with full disclosure;
* astroturfing the posts&comments;
* rigging upvotes/downvotes;
* building relationships with (maybe bribing) the mods; and/or
* entirely running the sub already.
