I think the point is not that VW should stop selling gas-powered cars completely yet, but that they should at least match Tesla in investments and strategy when it comes to EVs. Right now they are far behind, and that's beyond shameful - it could cost them the company in 10-15 years, because EVs are the future. And they are still not quite acting like they are.
They're still treating EVs as another "market segment" and that's a problem - for them.
