I don't know who actually ripped off who, if at all. But in terms of product name, if we go based on public launch date, the first generation of Pixel Buds were released in Oct 2017 and the first generation of the Amazon Buds were released Oct 2020 IIUC. Google Assistant was announced in May 2016, Amazon Alexa was launched in 2014. Disclaimer: I work at El Googs but not on these products. These dates I just searched on the web within 30 seconds.
