I think the huffing might be a side issue. Difluoroethane is a fair bit cheaper than tetra so suppliers are switching to it as a cost reduction measure.

Refrigeration industry still depends on HFC134a for automobiles as they cannot use flammable HFC152a (difluoroethane) so the various industries are picking their favourite fluorocarbons.
