Honestly, i don't get why people are bitching about it so much. A company, that makes a game with intention to make money off it, that never supported linux neither promised to support linux some time in the future, clarifies that it sees no purpose in supporting linux because of monetary reasons.

Okay, that may be your favorite game, you might have spend tons of money on in - but idea that it may never be supported on your favorite platform has never crossed your mind? It's like whining that PS exclusive game is not getting ported to Xbox.

So basically, “it’s too hard, and our engineers are not good at their jobs.”

Imagine this: you have a cheater problem. Your team of developers have only ever worked on gameplay-related stuff - graphics, game engine, etc. You can:

1. Make them pull solution out of their butts, somehow gain expertise in topic they have never worked on
2. Pour ALOT of money in HR and hire specialists that have experience in anticheat software
3. Pay 3rd party for solution that you can use RIGHT NOW and that works (at least somehow)

When money is involved, you make decision by counting them. You give somebody (tech lead, probably) task to evaluate your options - and give you approximate numbers. And i'm not surprised they chose 3rd option.

Stop stealing our CPU cycles for high risk rootkits and start mitigating and detecting cheating on the server. It’s that easy.

I'm currently working on bot detection for web resources - and trust me, it's extremely hard to distinguish them from people without some client-side analysis. Sure, you can use behavioral analysis, but you need lots of data and, again, expertise in that. Okay, they have the data - thousands of games played daily. Have you ever seen job listing for "game patterns analyst for LoL"? Again, you have to find someone capable - highly payed experts, who will spend some time testing their theories, with no guaranteed success.

"How do you separate good players from cheaters? This low ranked player who just got his second pentakill - is he cheating or smurfing? This weird behaviour - is it because of missing fog of war or are they just communicating over voice chat?"

It's just... really NOT that easy.

The “distributions” argument always smells like bullshit. Developers actually interested on supporting Linux usually stick to one or two distros of their choice. (Typically Ubuntu.)

There's your answer - they are not interested. And there is nothing wrong with that! It's just business! Remember the "a times b times c" scene from fight club? They've calculated their x - and it's not worth pursuing (for them).

Rootkits are bad, m'kay. Wanna avoid them? Don't install them. Just don't be surprised when company adds them - it's their product, they do whatever the fuck they want.
