I've been giving it some thought and personally I dont think its much of an issue. Could be wrong though kek
While Twitter is one of our main platforms, its not the only platform, and unfortunately its the only platform that has this inconvenience with images.
Also, not every meme is a winner, we dont really know who is grabbing our memes, if at all, and or where they are taking it to be distributed, if at all.
I try to keep it in mind and accommodate when I can, but not every image/meme is made for that kind of format, like movie poster size, for example.
It seems silly to me to waste a bunch of effort on making all these when the anon(s) that grab them can modify them to fit whatever size they need for what they are going to use it for just as easily as we could.
My 2 cents.
