No. but it is an increasingly obsolete view.
He, and others like him, have musical careers. They are getting paid to play. That it is not to your taste is irrelevant. That they are getting paid by advertising revenue rather than getting 2% of physical media sales is also irrelevant.
He is not releasing music on 78 speed vinyl, he's releasing it on youtube and he has built an audience over years of hard work.
And it is hard work. It's coming up with 4 or 5 new vids a week. Planning it, filming it, editing it. Dealing with copyright issues, etc etc. And that ignores the investment of the time needed to be able to play as well as he does. He's probably putting in more than 40 hours a week on it. That's a lot more than most musicians do, or even attempt to do.
Complaining about modern ideas is a weird thing. We are on this forum because we play an instrument that has only been around for about 70 years and was laughed at when it was invented. I suspect that when Bottesini asked for a 4 string double bass rather than the traditional 3 string one the response was "Why? What's the point?" as well. Things move on.
People like him do not affect the traditionalists ability to get pub gigs, or record what a traditionalist gatekeeper has decided is valid musical expression, or any of what has gone before. It's just something new to go into the pot.
And like or not - he's inspiring people to play. 99.9% of them will never reach his ability. But they are playing and increasing sales of kit and making manufacturers invest in more product ideas etc etc.
For some reason I had this view that bassists were somehow more rational than guitarists - many guitar forums are filled with people complaining that many new young guitarists say they were inspired to play by Ed Sheeran! Who GAF how they decided to pick up an instrument? The important bit is that they did!
As for the amazingly dim sounding "I bet he can't play in a band" type argument.... ye gods that's a poor argument to present. Loads of the flashiest players spend most of their day doing sessions for other people. Just holding down the bottom end, playing roots. Marcus Miller does it. Billy Sheehan does it. There is zero reason to think that someone who can play like CB cannot play what a song needs.
I used to play Classical Thump and Colorado Bulldog etc. And I had no problem joining a 25 member jazz big band and just playing what was written. I loved it just as much.
