Earlier quoted context omitted.
The "trivial" solution doesn't work. And they thus had to do the non -trivial thing and write their own custom text renderer. If I'm right in my reading, the author of the tweet is wrong to complain about them saying it's "trivial," because they never did.
A custom text renderer was exactly the trivial solution suggested and demonstrated to them when they claimed it was extremely hard and required a doctoral research.
For my point it doesn't matter if they are in the wrong, if it was easier than they claim, if they are rude, etc. All I'm saying is that the complaint on Twitter is that they now called something "trivial" that they said wasn't simple or easy before. They clearly didn't do that.
