This is so funny because rust has one of the worst cheating situations and majority of their players are windows users, and theres lots of games that have anticheat that allows linux and have notably less significant cheating problems like marvel rivals. in reality rust doesn't take cheating very seriously because if they did they would have more server side software that detects illegitimate behaviour like tons of other games do successfully...... even most popular Minecraft servers have better functioning anti cheat that is completely server side than rust has while getting kernel access to your pc. its pathetic and lazy development tbh and this entire post from them reads like such extreme cope....
One of the biggest Minecraft servers I know of had basically no anti-cheat and just relied on user reports and bans. And it was extremely effective. It was a PvP based server, and I only encountered cheaters in like 0.1% of games, and even then they were usually banned before the match finished.
Unfortunately this usually requires a dedicated mod team. For smaller servers it's not much a problem but when that scales up, companies often decide paying for an enormous dedicated mod team to review reports and make bans isn't worth it when there are cheaper (albeit shittier) options.
And then there is 2b2t where everyone cheats as much as possible.
