This is just appalling

It affects our game experience because it means more things get designed for the cash shop rather than for the game itself.

That's not true at all. We can look at a simple comparison of items added to the cash shop in 2017 (that were explicitly designed for the cash shop) versus items added in-game in 2017 (that were added as part of an event). Cash shop items will not include past event items, and here is why: because these items were once available for free in-game as part of an event, and were not designed with the Cash shop in mind.

Cash shop (2017):
--Barding: Angel Barding, Demon Barding
--Emotes: /playdead, /backflip, /easterndance, /easternstretch
--Glamour: Aymeric Attire, Heavensward Attire, Fuga Attire, Moogle Cap, Moogle Attire (including the two Moogle attire items even though one was originally a pre-order bonus for ARR and the other the Heavensward Fan Fest item)

In-game (2017):
--Heavensturn 2017: Red Tori Kabuto, Black Tori Kabuto, Happy New Chocobo, Heavensturn Orchestrion Roll
--Valentione's Day 2017: /dote, Angel of Mercy minion, The Kiss Orchestrion Roll, Paramour Vase
--Little Ladies' Day 2017: Songbird Attire, /songbird, Eastern Cherry Petal Pile, Little Ladies Day Advertisement
--Hatchingtide 2017: Egg mount, Eggstravagant Interior Wall
--Make it Rain 2017: Rainmaker hairstyle, 3 new Triple Triad cards, Stuffed Sabotender

And this isn't even including any new glamours, bardings, housing items, or orchestrion rolls added during Patch 3.55 ~ 3.55b. So, no. Items being added to the cash shop does not negatively impact the amount of items being added in-game. I think that this list is more than enough to prove that.

Let us also remember that some of the items (mainly those that came from China or Korea) had to be bought with real currency in their respective countries, and were brought over to other countries due to player demand. Yet, people in these other countries wanted the items added in-game for them for free, even though Chinese players and Korean players had to pay real money for them.

Prices of things could always stand to be cheaper. Ask anyone if they want things cheaper than current price, and only a fool would say no. However, no one else has control over what an individual does with his or her money except for the individual spending it. If it bothers people so much that others want to spend their money as they see fit (be it on a glamour item from the cash shop or be it on buying merchandise from the SE Store that has DLC attached to it), perhaps you should find a way to let something like that go. It's not like someone is using your money to buy cash shop items.
