I guess I don't see what the incentive would be for this, or even what it realistically means in this case.
Do you mean like relicensing the backend and frontend with a closed source license? I don't see what the incentive would be for that unless they wanted lemmyml to be the only instance in existence (which runs counter to it's raison d'etre) and to make secret/proprietary/commercial extensions to it that are difficult to develop in the open.
Or I guess unless they wanted to start charging instance admins for the honor and pleasure of running their software, which at least right now would be the quickest way to ensure nobody runs their software.
My wife got on stimulant meds after her diagnosis a couple years ago and they were life changing for her. She was having trouble getting them for a couple months during the shortage and that was tough on her.
Like another commenter mentioned, you'll probably wanna avoid caffeine for at least the first couple of weeks if you're taking the stimulant meds. Once you adjust, you may be able to do caffeine again, but you may give yourself a real bad day if you aren't careful.
