Which user(s) are you talking about here exactly? Now I don’t keep track of who-complains-about-what-and-when, but my impression is that people complain about time-limited DLCs…
- when they are announced, …
- when they are available and …
- when they are unlisted. …
… more often at multiple of these than only at (3) when they were indifferent at (2).
I think all three phases are valid time frames to complain about it, regardless if it is bought during (2) or not. For example a user could be sympathetic with more casual players who missed it for valid reasons regardless if the user decided to buy it themselves.
You started this whole string of replies to this post:
…and your limitation of users was not given there. It kinda feels like you constructed something just to give a counter argument for the sake of it. While, sure, someone should not complain if insert-situation-of-someone-who-should-not-complain but does that add something to the discussion here? In the end the DLC is either available for anyone, both hardcore fans and casual players, or not. The difference is not important for this main question of making the previous 2 DLC permanently available.
That being said, regarding you keep replying despite noticing things are repeating, I am reminded of this reply I did to you some time back:
