You sure showed us. : D
It's not about your spending habits, no one minds what you buy and how much.
People aren't boycotting the cash shop as a movement, and people didn't mean to tell you off. They meant that whatever is in cash shop isn't going ig.
Imagine all our minions weren't earnable for doing dungeons, buying with currency (gil/mgp/poetics), special fates, potd and so on, but strictly from cash shop, or even a consistent amount from cash shop. Then all those ig features that offer them are made more stale.
Similarly, if crafters wouldn't have outfits and minions they could craft they'd feel the loss, and so would the average player regarding accessibility.
You're too silly if you spend your money on things you don't care for (and therefore were buying anyway) because some person on a forum wanted something ig instead because this is paid subscription.
The interesting argument some people bring up is that the cash shop enables both taking from the people that can splurge, and using the money to make more game content everyone has access to.
