I am interested in paying donations to free and open source software I regularly use and have into my workflow. I will completely ignore your project if you make me deal with license keys. The Grayjay method is ok but would prefer that code and buttons not be dedicated to getting in my way. I hope that the mentality of paying for what you use becomes more common in FOSS culture so that prompts aren’t needed.
That said if your broke, don’t dontate. Take advantage of it being free and when you get a good job again, then consider helping out the developers.
In recent personal experience, I recently changed the motherboard on my Winblows VR gaming PC and It wouldn’t recognize my legit product key anymore. I don’t have patience for DRM shit so I activated it with KMS. Activation keys are a pain in the arse.
I emphasized It’s use for VR gaming just in case someone tries to sell me on the Linux Proton compatibility system. Someday soon steamVR will hopefully have good compatibility and I will give it a go. However I will always at minimum be stuck with windows on a secondary ssd as I have some Oculus games I also like and Oculus+revive will likely never work under Linux.
