When a company decides to put shareholder profit above customer engagement and availability, it shouldn't surprise them when people don't want to engage with that brand anymore.
Sounds like Nike wants people to think it cares about running only when it sees that its profits as a collectors item fade since less and less people have disposable income for shoes. My Nike fund can't build up when all my extra money now goes to the grocery store, mortgage, and energy bills.
Any reasonable changes to restore face with the running community would mean eating into profits, which shareholders won't like, and they can't publicly say they need to do it to save the brand.
