IMO there is no way a musician name drops a product without collecting a bag. The interview with Amazon would also have cost them money to make happen.

Weezer would need to be astonishingly naive to write the song before the agreement was reached with Amazon. Also other comments in this thread detail their past record of selling out.

I listen to quite a lot of hip-hop and there were a couple of years about a decade ago where almost every artist had a lyric about uber.
