Is TLauncher illegal?

TLauncher is a safe program, BUT there is a heavy consequence on using Tlauncher as your main Minecraft Launcher. Using Tlauncher means that you’re violating the anti-piracy act. Some players used it and there are still using it, so far there’s no causalties on using it.

Also with TLauncher, you cannot join official Minecraft servers such as: Hypixel, Mineplex, etc. Be sure to buy Official Minecraft Launcher though, there’s a lot of advantages on using the official one.
