I've seen companies say they are doing things when there is hard evidence of them not doing a single thing. The fact the game is a mess and you have desync issues effecting matches, to people who do not know what these things are, they can appear as cheating. Also the fact I've seen blatant aim bots and other hacks in matches backs up what this guy is saying. I report everyone I see, or suspect. I've seen people running around with sniper rifles using them like shot guns and getting nothing but head shots. people with SMG's getting nothing but head shots at 200 meters plus, tanks instantly snap aiming at you. They are there and have been more prevolant since the free weekend.
You can also use vague terms and percent of matches as much as they want, if they don't give context, it's like in an advert where they say 90% agree, and in small text at the bottom you have a random number of people like 137 people, so they could get the numbers to that percent. 3% of a million matches is still 30K infected matches.
