I mean, you can grasp onto your cooperate greed narrative if it helps you feel better about yourself - but when it comes to the maintaining the goodwill of its player base - The Dev team still has quite a bit of capital to spend.
The argument you're making is one in isolation, spoken in admitted ignorance (been gone since early heavensward), and presumes ill will at the worst concepts.
You know what populates mogstation the most?
Items specifically requested by the playerbase that fell outside the typical development scope of additions. The fact that FFXIV has a dedicated team to adding items to the cash shop - separate from the normal development team - means that they have a team that self sustain and reach out to player needs without vastly impacting the base. Reallocating these people will not provide these items in game, because it would still have to be budgeted inside the existing structure.
Why am I mentioning this old fact? Because you seem to think that they're stripping staff time and budgets specifically for the cash shop. And that has never been the case in this game. They are septate groups with specific tasks. Both were impacted by the pandemic, but you'll never know what got delayed or canceled from Mog Station because we don't have a planned out, reliable schedule from them to keep them to, aside from seasonal items from past events coming back up for sale.
What we can see, is the impact on the event team from the pandemic and other issues.
Your claims have zero basis in reality - this system was spelled out to us years ago.
The better augment is to direct them into what sort of mounts you want within the scope of reward structures we have, and to suggest them be implemented in different ways. As far as events, it's a down year. I don't think this is sinking in, but we're still in a pandemic we're likely going to be feeling the effect of that in the workspace until mid next patch cycle at least. I suggest you set your expectations accordingly.
We're not lacking for events, or mounts, or whatever because of the MogStation crew. If we did not have the Mogstation crew you wouldn't have these items at all. That staff would likely be allocated to a different part of the company.
