I'm imagining Vistani run caravanserai. They're neutral territory so the darklords could theoretically even meet there (with most of their abilities "turned off"). Some characters might stay there for a year+, but eventually their ability to pay runs out and so they need to leave.
What is the point of these comments? Is it to belittle people who in the past have had negative stereotypes perpetuated about them in D&D material? Is it to denigrate any company that tries to be more inclusive? I just don't get it.
Also please don't reply with "iT's JuSt A jOkE".
