I didn't read anything one time in weird corner of the internet like seem to want to insinuate. There are plenty of sites where you can see the items being tracked. There is a large number of second stages in orbit that are not coming back any time soon. It might have been some coincidental bit of luck that on one particular perusal of one of these sites I just happened to click on 2 such items. Again, as they continue to increase the rate of launches, this will become an issue. And obviously, I don't believe SpaceX is the only such party doing this. That's just an unintelligent comment to have made.
You seem to be saying that all entities globally should as a whole launch less objects into space, as you imply that putting more objects into space is a net negative. That's fine to think but I strongly disagree that we as a planet should launch less objects into space.

I agree, which is why we should push for regulations that require satellite operators to have plans to de-orbit their satellites at end of life and/or not launch to orbits where the launching stage cannot quickly de-orbit within a set number of years. However simply pushing for all countries to launch less things into space, as you seem to be saying, is not a good idea.
Also, this isn't just SpaceX, every launching country/company leaves second stages in orbit, some, unlike SpaceX, don't even try to dispose of their second stages and leave all second stages in orbit.
I'd recommend reading up more on the topic as I think you read something at some point and think that SpaceX is an especially bad actor in the space when in fact they are one of the most responsible actors, if not _the_ most responsible actor, in the space launch sector at the moment.
