This is an excellent decision made by these retailers and brands. The burden of Covid-19 needs to be shared across the supply chain; it is not sustainable to put all of the short-term pain at one end of the supply chain. 

Retailers need to think strategically about supply base relationships and how to come out of the crisis with the partnerships they need. This crisis is likely to have a long term impact on sourcing strategy, flexibility / security of supply chain, inventory management and apparel assortments. Those that start thinking about this early will be the winners in the long term.
