YT Support Confirms Inactive Subscribers Hurt New Videos Getting Pushed - True?

I have a YouTube channel that deals with playing claw games, arcade ticket games, coin pushers, etc. It's pretty old and some videos that went viral were trends and obviously a lot of subscribers that sub for the trend don't watch the channel anymore. I still have a decent loyal fanbase but kept prying YouTube support for answers on why my newer content isn't getting pushed like it used to. They kept coming back with long generic responses until finally I asked and quote:

"Again another generic answer that doesn't just straight up answer my question. Sorry but you gotta see why I'm frustrated. Can you just answer me a yes or no that  "DOES SUBSCRIBERS THAT NO LONGER WATCH YOUR VIDEOS HURT YOUR UPLOADS GETTING PUSHED, IF YOUTUBE SUGGESTS THE VIDEO TO THEM AND THEY DON'T CLICK ON IT"? (AKA Subs that don't watch your content anymore)"

they reply:

"I hope you're doing well.

Yes! 

Have a nice day!

I kept suggesting that YouTube should allow creators to go thru and remove accounts that are subscribed but no longer click new videos, if in fact this is hurting new uploads from getting pushed. I know Youtube does clean up accounts but they have to be deleted or completely deactivated already.

Would love to know thoughts on this. Or maybe they replied this to just shut me up LOL. ?
