Is it really weeding out fickle players when they announce their leave because the GM has been neglecting a roleplay?

Follow-up question: is this the right thing to do when someone voices their reasons for bowing out to you for future reference?

That entirely depends on your definition of “neglecting” a thread, I suppose. It would be important to understand context and actual communicate with the GM if they are actually neglecting their work that they put a lot of effort into rather than making assumptive deductions. But to answer your question, yes, it is weeding out fickle players who have no dedication to an admittedly slowly paced collaborative project. Perhaps it would be more agreeable for players to contact a GM rather than creating their own narrative. 

Also, I don’t buy into the idea that I shouldn’t be allowed to state my frustrations in a thread designed for it just because I’m an active GM and people [former players] can see what I’m posting. If they feel it disheartening, it is understandable and I should recognize the consequences of that action. There is really no argument about that. To elaborate on my first sentence, I don’t subscribe to supposed moral beliefs if something is or isn’t the “right” thing to do because they are absolutely subjective. You are welcome to disagree in the discussion of free thought on it, but it will not change what I am doing and will continue to do.
