>>16012466Ask yourself this: Even though the gamer maid is no more, do you still enjoy her contents(utawaku, zatsudan, concerts, skits) that she/the official Hololive channel put out irregularly even just a bit slightly?
If you do, then please continue supporting her from now on. There might be a day where she starts playing some games in a streak again, however slim that chance is.
If you don't, then hit that unsubscribe button, and move on. You said it yourself, the girls will mature, change and move on, and so do you. You might find another one that fits the criteria of what you're looking for, and be happier supporting them instead.
