What makes you believe it is a shtick?
When there is drama as far as I can tell he always had pretty solid reasons to be dramatic. It isn't drama when you have real reasons. Drama implies making shit up. Point to the shit he made up. Go ahead. Be specific.
Your accusation there makes it sound like he makes up some minor personal issues and blows them up as rage bait. As if the lock in and enshittification he advocates against are just his personal opinion. They are not. The vast majority (last time I checked >80%) of the public shares the opinion that you should own the equipment you buy and that it should be repairable.
If you happen to be a person that tries to establish neo-feudalism at the cost of everybody else, a public figure successfully making that an issue, might be problematic for your goals, sure. But then your goals may just be beneath contempt anyways and you should working on becoming a productive member of society instead.
If you think it is a shtick because you haven't really looked into it that much and you have a contrarian reflex, maybe try to bring the receipts next time. You know, like:" Louis Rossmann is a drama queen because remember when he said X about Y? Remember when he said Y about Z? It turned out to be Q and Louis had to know it was Q" etc.
Rossmann turned his YouTube fame into political advocacy for a popular topic, that he politically represents. Don't like that topic? Don't watch his content. People change and so does the focus of their life.
I run an university electronics workshop and the issues he mentioned are the issues I have to deal with every week, be it some shitty vendor lock-in on some gear or equipment where just the part that dies first is proprietary and service-hostile.
