I think it’s because “Tesla vs BYD!!!” is an interesting story for the media, whereas “VW AG continues to make vast quantities of boring cars like they have been since the 60s, only now some of them are electric” is a very boring story for the media. So you get lots of talk about BYD and Tesla, and very little mention of the boring legacy manufacturers who actually make most electric cars (in the UK and Europe; other markets are more Chinese-dominated)
