I think it's neither. They just recently did a very good job at developing several young riders that will all need pay rise so some of the older guys had to go to make room for it in the budget, just like Quick Step was losing strong riders year after year but still staying strong a few yers ago.
In my opinion Ineos is too big of a team for having such low ambitions. I mean it's good to have talented kids around. But i do imagine that for a team such as Ineos that is not enough. Not by a long shot.
