The Problem:

Roblox, although not having native support for Linux, was at least playable via Wine. Unfortunately, that is not the case anymore. Roblox has blocked Wine in a recent update. Moreover, this situation is even worse for users who use Linux as their sole operating system. Lastly, these actions were completely intentional as stated by this staff:

"Hello Jrelvas, Unfortunately this block was intentional. With the Windows 64-bit client launch we made the conscious decision to block the use of Wine. We came to this decision due to a combination of security and compatibility concerns. As a Linux user I am sure you understand the challenges of the Windows ecosystem. Wine is not officially supported but we are committed to working towards compatibility where possible. Unfortunately, I cannot provide a specific timeline for this support. However, I assure you that it remains a priority for our team."

Solution:

If Roblox were to unblock Wine, that would be great, but what would be most preferred would be for it to actually release native support.
