I'll be honest ... maybe you're right but it's not really my concern. I've got a billion other things to care about that are more important; you probably do too.

Seems to me like the video author is just trying to make more drama ...

This sort of thing always happens anyways, some new thing comes along (systemd), some people want to use the old thing (sysvinit). Some people are like ... "god why would you use that, you're so dumb" ignoring any valid use case. Some other people fought very hard to convince people the new thing is great, so they've got a personal stake. (etc... etc..)

It's not sinister, it's at worst just people being annoyed that others are trying to hold onto the flame when we have light bulbs; my two cents.
