To put this in context, Marvel went bankrupt in the late 90s. The comic book business was in collapse, their movie rights were all over the place and had never been used to make anything except a few risible B films, and there was much talk of The End.
They seem to be doing okay.
My point is that once an IP reaches a certain level of cultural saturation, it's really hard for it to go away, barring massive cultural shifts that are way outside its control. It might languish for a time, but there will be a reservoir of awareness and nostalgia that keeps it alive and ready for a resurgence. D&D has that level of cultural saturation - in fact, that is what is sparking Hasbro's talk of better monetizing it.
So OP has the right attitude - just keep playing it how you like and making more great adventures.
I need to do a better job of ignoring all the agitated threads that jump onto whatever the latest rumour is and go into a frenzy. I find them frustrating because it feels to me like a lot of folks are just here to root against D&D, or against the current version of D&D, and I don't understand why that's a thing. So I start arguing and become part of the problem.
Edit: I love D&D. I have since I was introduced to it at 12 years old. I run the D&D Club at my school, and the game has made such a positive impact on so many kids. Last summer, I ran my first summer camp for mostly neuro-divergent kids, and they were so happy - I cannot tell you how many parents were just thrilled that their child was excited to be with another group of kids, socializing and having a great time. I have had parents tell me that their child never had a real friend before they started playing this game. I talked to one mom on the phone who was crying, telling me that her kid, who had never had a single friend over, just had a D&D birthday party with 7 other kids at their place, and now they play every weekend, almost.
I get that other RPGs are great, too. I play many of them, and I introduce students to them, too. But D&D is the thing that everyone knows about - it is the gateway for almost all these kids. I have seen it have such a positive impact, over and over. So I root for it to keep doing well, and I get defensive of it. And WotC has sponsored our club via access to a ton of free stuff on DnDBeyond, and I want to speak up for that. Painting them as corporate villains really rubs me the wrong way, because in my direct experience they are the opposite of that.
Edit 2: Each time I read this thread's title, the voice in my head sounds like Wooderson from Dazed and Confused (Matthew McConaughy's character). Just keep p-l-a-y-i-n'.
