This failure falls straight into ED's lap. When VEAO failed to meet any contractual timelines that were established between the two parties, their product should have been suspended against further sale and a warning issued for breach of contract/timeline. But we know how poorly ED holds a timeline in regard, so thats a "Meh".
Lastly, ED's failure to notify the 3rd parties of the internal code changes further exasperated the situation when VEAO didnt have the skills to code and keep up.
I'm truly curious how the other 3rd parties are being handled, that have not produced needed updates. Polychop, Mag3? Even Mil-Tek 5 with the nearly vaporware Bo-105. Come on, just call it quits already. By the dev time they've shown as a side job, imagine how long updates will take.
