That's all just talk.
They could hire 200+ engineers and they WILL. NEVER. STOP. CHEATING.
1. It's Free to play. Get banned, get another email address, keep playing. If they hardware ban, there are EASY ways to spoof your hardware IDs.
2. The people making the cheats get tons of money from the losers who want to use their cheats. They are funded better than the devs.
3. If a cheat gets detected, the cheat is updated and bypasses detection.
4. Even though it's a violation of the EULA, Respawn won't do anything if they catch a hacker. They won't charge $5000+ fines, they won't mandate prison sentences or community service... cause it's bad PR (go figure; that's the society we live in; we vilify the corporation for protecting its livlihood and property) Besides, the financial cost to take these people to court doesn't warrant the time and effort.
5. Respawn knows for a dev that gamers talk big, but they forget even bigger. As much as cheaters ruin your experience. You'll forget by the time Apex 2 comes out, and you'll go all in on that game too, being just as baffled when it, too, succumbs to cheats that Respawn just gives you lip service on that they're handling.
Pft. The the rate of QA failure I've seen lately; they have bigger issues than rampant hacking.
