They can tell us whatever they like. They are financially incentivized to find a scapegoat, which takes away their credibility completely. The fact is that Respawn has had a massive cheater and hacker infestation ever since the days of Titanfall 1 and continuing with Titanfall 2 and Apex. It's been an issue for longer than Linux gaming has been a factor, and smearing it on one part of the playerbase will do fuck all to resolve the deeply seated issues with Respawn's shitty software.
Fuck EA and fuck Respawn.
