Consider that their primary audience is close to 40 million mostly kid players. Young kids generally don't care about OS options and use whatever PC their parents buy, which will mostly be Windows. Further, even Windows PC players are in the minority, with close to 75% of users playing on mobile devices. Linux would always be a minority option. In the case of Roblox, it would be the minority option of a minority platform. Not really the type of thing the company is going to throw money at while they're supporting 4 other platofrms: Windows, MacOS, iOS, Android. All of them more accessible to their audience. Disappointment in their choice not to develop for Linux is natural, but it's a fairly reasonable choice on their part to avoid increasing their platform & build maintenance requirements by 25% for an exceptionally small number of users that would refuse to use a different OS.
