It's a bit judgmental, though the original complaint is also a bit whiny.
The reality is that Turtle couldn't make the business case to port to Cocoa at any point for 18 years, probably because most of their customers were Windows.
That's not them being lazy, that's just them directing their resources according to market demand and engineering constraints.
And Apple is not being greedy or uncaring, they also have to direct resources according to market demand and engineering constraints.
If Turtle had more Mac customers, they'd have either ported their app, or they'd purchase a Carbon compatibility library. And if more developers were actively using Carbon, Apple would put more resources into it.
They aren't, and so the two are going to part ways.
