It's not just Polygon to be fair. There are large parts of the games industry, and the gaming press in particular, that are so full of bad habits that it's essentially become toxic to it's audience, existing to generate clicks, hype and FUD, with little actual fact checking and reporting in between.
This is to take nothing away from Titanfall, but as Jason from Kotaku sad earlier, threads like these and reviews from Polygon, Gamespot et al right now are offering the sum total of jack shit to their audience, because despite their obvious hype and enjoyment of the game at the review event, 24 hours from now the game could be an unplayable mess because of server overload as the game is released into the wild.
SimCity, GTA V, and Battlefield 4 have all gotten free passes from certain outlets at launch, and these editors who were supposed to be informing people were quite happy to let people waste their money by outright failing to do their job, as long as they got their clicks.
Thankfully, the community is starting to wise up. It's just a shame that certain sites and companies are profiting by conning people out of money by releasing and endorsing faulty products.
