I'm well aware of this.Amazon owns a 17% stake in Rivian and Rivian still sells electric delivery vans to Amazon.
The only change was that contractually, Rivian was not allowed to sell electric vans to anybody but Amazon until recently -- that was part of the deal for Amazon's investment (temporary exclusivity). But Amazon is still buying Rivian electric vans -- they are just no longer Rivian's only customer for electric delivery vans.
Amazon is taking 10k/year which doesn't seem to jive with their original 100k by 2030 target.
