No, it is not usually. Here's another user that mentioned that their sub is running out, a rather well-known criticizer of FF14 that many of the "white knights" hate: https://forum.square-enix.com/ffxiv/...53#post6292453
And they haven't posted in 10+ days.
I guarantee you, if you look up the people who say that their sub is running out/are quitting and actually compiled the data, at least 80% of them will actually have quit.
Please try to prove this assertion wrong by finding someone who said they'll quit and have not, because I can find five times as many demonstrating the opposite.
