Tbf this
is also from the same company that just outright tells you that the Jagex Launcher and Jagex Accounts (which, in the future, will be required to use to play both OSRS and RS3 - as opposed to just having to have two separate standalone clients) will not be supported on Linux.
Of course, to their credit, they
do link to someone's Github that has several community projects designed to allow for the usage of the Jagex Launcher and your Jagex Account on Linux as well as a discussion thread on the official OSRS subreddit about getting it to run on Linux. (Basically there are a couple of third-party repackagings of the official launcher and a native third-party launcher, I use the latter because I just couldn't get the repackagings of the official launcher to work properly)
