A few weeks ago there was this article posted here about why some game companies are trying so hard to kill their old video games and give 0 shits about preservation (as in delisting them from stores, not selling them anymore, etc.).
One of the answers given by the publishers in the article basically boils down to “old, preserved games would compete with the newer ones and eat into their sales”, which does say quite a lot - they don’t care about losing sales of older video games, all that matters is the sales of the newer ones, preservation be damned.
Don’t fall into doomerism - news companies are companies, and negativity gets people on their platforms for much longer than positivity, it’s easy to get addicted to it. Set time limits or limit the amount of news you consume per day/per week.
Recognize that caring about something requires mental energy - if you had 1 friend who asks you to care about their hobby or learn a bit more, then you might agree, but if you have 20 friends with different hobbies asking the same thing, then there’s no way you can care about all of them. Similar thing applies to the news, recognize that you can’t care about everything and try learning how to stay informed without giving up lots of mental energy stressing about things you can’t really influence.
It’s admirable wanting to keep up with the news, but it also can be a bit of a trap and does require a degree of skill to not fall into what you describe in your post.
