I wholeheartedly disgree with the image description. While it should have been Twilight making the decision at the end instead of Celestia taking over for some ridiculous reason, the resolution is fine. Friendship is magic, but neither friendship nor magic are perfect. They don't make it always possible to successfully turn someone around, and learning you sometimes have to put your foot down is also a good lesson. Redemption requires participation on both sides, and these three clearly showed that they were not willing to give an inch (and no, Cozy being a child matters not one bit when she's been consistently portrayed as the mental equal to a full adult in every way). Recognizing that some people can't be swayed by forgiveness and second chances is fully consistent with all that the show has presented, and doesn't contradict any messages or character arcs at all.
Plus, regardless of what Discord says, turning to stone isn't definitively permanent, which keeps the door open to the situation regarding those three turning around someday down the line.
The Ending of the End is definitely flawed in a number of ways, and it's pretty cruel of the writers to tease the reformation of the three in Frenemies if they were going to have them go down fighting in the end, but the events as a concept aren't antithetical to the characters or the show in the least.
